DWG is the native and proprietary file format for AutoCAD® and a trademark of Autodesk, Inc. LibreDWG is neither associated with Autodesk, nor with the Open Design Alliance.
LibreDWG is a free C library to read and write DWG files. The DWG file format is proprietary and was created in the 1970s for one then-emerging CAD application.
This library is part of the GNU project, released under the aegis of GNU. It is made available under GPLv3+, i.e., under the terms of the GNU General Public License version 3, or (at your option) any later version.
It came out of code from the QCad Community Edition product from Ribbonsoft.
LibreDWG 0.13.4 provides the API/ABI version 1. We hope that this doesn’t need to change much in the future.
See include/dwg.h for LIBREDWG_VERSION_MAJOR,
LIBREDWG_VERSION_MINOR and LIBREDWG_SO_VERSION.
Because the DWG file format is not open, its specification had to be reverse-engineered. The specification is almost complete. The LibreDWG implementation of the specification is an ongoing process; as of version 0.13.4, coverage is approximately 99%.
It can read all DWG formats from r1.2 to r2018 for 99%. The internally supported DWG revisions are identified as r1.1, r1.2, r1.3, r1.4, r2.0b, r2.0, r2.10, r2.21, r2.22, r2.4, r2.5, r2.6, r9, r9c1, r10, r11b1, r11b2, r11, r13b1, r13b2, r13, r13c3, r14, r2000b, r2000, r2000i, r2002, r2004a, r2004b, r2004c, r2004, r2007a, r2007b, r2007, r2010b, r2010, r2013b, r2013, r2018b and r2018.
Here is a list of features that are still missing:
Writing DWG formats for r2004 and later: r2007, r2010, r2013, r2018 is an
ongoing effort. You need to patch the code to enable writing to the r2004+ format.
See the work/2004 branch.
Writing to the specific r2007 format is not implemented.
We write as default in the r2000 or older formats only.
DXF support is now mostly implemented. ASCII DXF’s are generated fully, with much more elements and fields and other free libraries, but AutoCAD ® fails to import some of them. See the TODO file for a detailed coverage report.
Reading binary DXF should be complete but is undertested.
Reading and writing pre-R13 DXF’s is work in progress. There is no support planned for the very old pre-R2.0 DXF format.
For a detailed overview see the file src/classes.inc or src/classes.c.

Some projects that use DWG (and specifically LibreDWG) are:
Plans are to add support for SolveSpace, LibreCAD, FreeCAD, OpenSCAD and PythonCAD.
Related libraries:
The old version (documented in Esperanto) which was forked to LibreDWG in 2009. But in the meantime it got a DXF reader.
Read the DWG format for all versions r13+ but with much less elements, only those needed for DXF. Written in C++, under the GPLv2 license.
Read the r2000 DWG format. Written in C++, under the GPLv2 license.
Read and write the basic objects in most DWG and DXF formats. Written in C#, under the MIT license.
The OpenDWG’s license does not allow the usage in free software projects.
Compared to libdwg, libdxfrw and libopencad, LibreDWG can read and write much more DWG versions and details. Which is especially important for attached links and data from third party applications: BIM, MAP, GIS, AEC, MECH, ..., for 3D solids and dynamic parametric constraints.
This chapter describes how to compile and link a program against LibreDWG. To access LibreDWG interface elements (see Types, see Functions), include its header file in the C code.
#include <dwg.h>
Optionally you can also use the
#include <dwg_api.h>
API.
Make sure you specify ‘-lredwg’ when linking, such as in this Makefile.am fragment:
AM_LDFLAGS += -lredwg
Note that the shared object library is named libredwg (with some
system-specific extension, e.g., .so), so you do not
want to specify -llibredwg, as that would (try to) link against
liblibredwg and fail.
LibreDWG types map closely to the type system of the DWG file format. This chapter describes the enums and structs used to define the single DWG structure, which is passed around the functions (see Functions).
BITCODE_RC char ¶1 raw unsigned char, uint8_t
BITCODE_RS short ¶1 raw unsigned short int, uint16_t
BITCODE_RL long ¶1 raw unsigned long int, uint32_t
BITCODE_RD double ¶1 raw IEEE-754 double
BITCODE_B byte ¶1 bit
BITCODE_BB byte ¶2 bits
BITCODE_3B byte ¶1-3 bits
BITCODE_4BITS byte ¶4 bits (for VIEW view_mode)
BITCODE_BS short ¶1 bit-encoded unsigned short
BITCODE_BL long ¶1 bit-encoded unsigned long (max 32bit)
BITCODE_BLL uint64_t ¶1 bit-encoded unsigned 64bit long
BITCODE_BD double ¶1 bit-encoded double
BITCODE_DD double ¶1 bit-encoded double with default
BITCODE_MC long int ¶1-4 modular chars
BITCODE_UMC long unsigned int ¶1-4 unsigned modular chars
BITCODE_MS long unsigned int ¶1 modular short, max 2 words
BITCODE_BE double[3] ¶1 bitencoded extrusion vector.
Note that this specifies an OCS (Object Coordinate System) for each entity, with the default (0, 0, 1). An extrusion of (0, 0, -1) is typically caused by exploding a block inserted with a negative x scale, i.e. the sign of each X point needs to be flipped. For more see the vendor DXF documentation on OCS and programs/geom.c.
BITCODE_BT double ¶1 bitencoded thickness value
BITCODE_TV char* ¶length + ASCIIZ string The default text type until r2004.
BITCODE_TU wchar* ¶length + windows 2-byte wchar string (UCS-2). The default text type since r2007.
BITCODE_TF char* ¶Fixed length buffer, which can include NUL characters.
BITCODE_TFF char* ¶Embedded fixed length string, which can include NUL characters.
BITCODE_H void* ¶handle-references
BITCODE_CMC struct Dwg_Color ¶Dwg_Color struct with index or rgb, alpha and optional DBCOLOR handle, name, book_name.
[and some more]
Two types that do not derive from the type system of the DWG file format are the enums for return codes and error codes.
On non-C99 systems ensure that stdint.h and inttypes.h are available
to use the proper C99 int32_t,... types, and not just the
native fallback types int/long, which are different across platforms.
All header variables.

The r2000 format (used for r13-r2000) knows the following 6 sections:
HEADER CLASSES HANDLES OBJFREESPACE + 2NDHEADER MEASUREMENT/TEMPLATE AUXHEADER (only r2000)
The r2004 and r2007 format (used for r2004-r2018) knows the following sections:
R2004_Header UNKNOWN SUMMARYINFO PREVIEW VBAPROJECT APPINFO APPINFOHISTORY FILEDEPLIST ACDS REVHISTORY SECURITY OBJECTS OBJFREESPACE TEMPLATE HANDLES CLASSES AUXHEADER HEADER SIGNATURE INFO SYSTEM_MAP
The old pre-R13 formats (from r1.1 to r11) have those sections, with the tables interleaved into the HEADER.
HEADER ENTITIES BLOCKS entities EXTRAS entities
With (from r1.1 to r10) those 5 Tables:
BLOCKS LAYER STYLE LTYPE VIEW
With r11 came the additional tables:
UCS VPORT APPID DIMSTYLE VX
But we convert them internally to r2004 table record and table control objects. See Tables.
The OBJECTS Section is usually split up into multiple pages (separate sections of type AcDbObjects) and contains all entities and objects. It is indexed by HANDLES Section.
See OBJECTS.
The Classes Section contains the basic info for all dynamically loaded types for entities and objects. Its types start with 500, and are variable. An entity which has no class loaded is displayed as proxy.
LibreDWG contains support for many classes, but not all. See src/classes.inc and src/classes.c. We define a stability for each class, one of stable, unstable, debugging and unhandled.
Objects in stable classes are treated as the fixed-type objects with full support. Changes are treated as API breaking.
Objects in unstable classes are sometimes written to DXF or JSON, but not to DWG. Changes are not treated as API breaking. Usually such objects are converted to UNKNOWN_OBJ or UNKNOWN_ENT objects, and when written to DWG converted to PLACEHOLDER, DUMMY or POINT objects with EED pointing to the original class and content. Only when rewriting from-to the very same version with the full known unknown_bits blob (e.g. dwgrewrite or json) such classes can persist as such.
Objects in debugging classes are only handled with the developer configure --enable-debug flag, otherwise ignored. See unstable above.
Objects in undhandled classes are always ignored. There are no fields known, only its type.
The Handles section contains a sorted list of all object handles and its position in the Objects stream. All values are stored relatively, as offsets. Handles only increase and can contain holews when an object is deleted, offsets can jump back also.
The R2004_Header section at fixed position 0x100 in the DWG contains some meta-data for r2004 sections to find the two important sections INFO and SYSTEM_MAP.
The content of the UNKNOWN section with type 0 is unknown and does not always exist.

The optional Preview section contains the thumbnail stream of BMP, WMF or PNG data of the drawing. Note that blocks or proxy objects can also contain its own preview fields. The program dwgbmp can extract the preview image from this section.
The AcDsPrototype_1b DataStorage, used mostly for binary ACIS blobs, embedded fonts, ...
The old pre-R13 formats (from r1.1 to r11) have no objects and no sections, just tables, which we store in the sections indexed by the enum Dwg_Section_Type_r11.
BLOCKS LAYER STYLE LTYPE VIEW
With r11 came the additional tables:
UCS VPORT APPID DIMSTYLE VX
Since r13 all those tables are stored as table control objects and tablerecord objects.
From pre-r13 DWG’s these tables are imported as old r11 sections and
as new CONTROL objects, so that all entities are accessible via the
single BLOCK_CONTROL.model_space -> BLOCK_HEADER.entities iterator,
all layers via the LAYER_CONTROL.entries -> LAYER objects, and so on.
All blocks are accessed via all other model_space BLOCK_HEADER’s,
get_first_owned_block (BLOCK_HEADER). Each CONTROL object
holds a list of all table records, i.e. entries. Each table record
entry has a name and other common table fields.
The VX table (also vport_entity table) is a special table until r2004 for VIEWPORT entities, which are VPORT extensions, esp. for Paper Space, but have no old-style table records. So VX_CONTROL contains a list of matching VX_TABLE_RECORD’s, which are pointed to by VIEWPORT.vport_entity_header handles. Likewise the VX_TABLE_RECORD object links in its viewport field back to the VIEWPORT. The VX table is not represented in DXF, on DXF import we need to create them with the VIEWPORT entities.
Before R13 we had no objects, just the 5-10 tables, and the entities divided into 3 sections. The entities, the blocks and the extras. Blocks just contains the entities from each BLOCK to the ENDBLK entity.
Extras contain entities which had no room in the original section, e.g. when closing a polyline, which needs one additional byte. Thus the original entity is replaced by an undocumented JUMP entity, which gives the offset into the EXTRAS section, until a JUMP in the EXTRAS jumps back to the next original entity.
See e.g. r10/entities.dwg
The JUMP [31] replaces the POLYLINE_2D entity which got later closed. An open POLYLINE_2D needs size 8, but closed 9 bytes. Hence they added the new closed replacement to the extras section at offset 0, index [66], and added another JUMP [67] back to the next original entity. Here it jumps back to the VERTEX_2D [32] at offset 0x84f.

The entity iterator knows about these jumps. The DXF structure resolves those jumps, and inserts the replaced entities.
“Extended Entity Data” (EED) may be optionally attached to each object. They consist of a handle to the registered APPID, and a list of typed data. Each block is preceded with a size, the processing stops with size 0.
Internally libredwg stores each eed line as an array of num_eed structs. If the size > 0, then new block starts with a handle, an optional raw string (when reading from a DWG), and a number of typed data entries. Only the first eed struct of each block has a size, all subsequent eed structs have size 0.
Example:
EED[0] size: 109 [BS] EED[0] handle: 5.2.762 EED[0] code: 70 [RC] short: 2 [RS] EED[1] code: 70 [RC] short: 0 [RS] EED[2] code: 70 [RC] short: 0 [RS] EED[3] code: 11 [RC] 3dpoint: (0.000000, 0.000000, 0.000000) [3RD] EED[4] code: 11 [RC] 3dpoint: (1.000000, 0.000000, 0.000000) [3RD] EED[5] code: 11 [RC] 3dpoint: (0.000000, 1.000000, 0.000000) [3RD] EED[6] code: 11 [RC] 3dpoint: (0.000000, 0.000000, 1.000000) [3RD] EED[7] size: 6 [BS] EED[7] handle: 5.2.763 EED[7] code: 70 [RC] short: 0 [RS] EED[8] code: 70 [RC] short: 0 [RS] EED[9] size: 23 [BS] EED[9] handle: 5.1.12 EED[9] code: 0 [RC] string: "RTMaterial" len=10 cp=30 EED[10] code: 5 [RC] entity: 0x6507000000000000 [RLL] - size: 0 [BS]
These 10 num_eed structs consist of 3 blocks with 3 size and handle entries. EED[0] starts with size 109, the handle pointing to object 762, 3 shorts and 4 points. The next block at EED[7] has size 6, the handle pointing to object 763 and 2 shorts. The last block at EED[9] has size 9, the handle pointing to object 12 (the APPID.ACAD application) and a string and an entity reference. The size is calculated by the needed room for all data code + values, without the handle. E.g. EED[7] size: 6 is 1 + 2 for EED[7] RC + RS, and 1 + 2 for EED[8] RC + RS.
Each data block consists of a RC code, and a variable value. A string may be a an old pre-r2007 ASCII string with a RC length (max 255 chars), a codepage and the string. Or a r2007+ wide string with a RS length (max 32767 chars) and a UCS-2 wide string.
decode stores both, the raw data, and the structured data. in_dxf just the data. encode prefers raw over the data.
XRECORD XDATA are very similar to the EED array, but internally it is a single linked-list, consisting of something like the EED data code + value pairs. There’s only one size, xdata_size, and only one handle to the APPID, which handles this XRECORD XDATA.
You can use LibreDWG immediately upon loading, without any particular
initialization. Only when using some see dynapi functions you might need to
initialize the version via dwg_api_init_version(&dwg), when you
need other formats than r2000 and you call an API function which does
not store the version internally. Most do. This limitation will soon be fixed.
You usually use one set of functions - either decoding or encoding - at a time. All functions use the common data types (see Types). All functions return an error code, and the high-level functions for multiple objects add the error bitmask, which is sorted by severity. When the error exceeds DWG_ERR_CRITICAL, processing is stopped.
The new see dynapi has dynamic get and set functions for all objects and its fields. You can get and set a property value from any object pointer by the object name and the field name.
The highest level function for decoding a file is dwg_read_file.
int dwg_read_file (char *filename, Dwg_Data *dwg) ¶Open filename and decode it, saving information into dwg. Return 0 if successful.
You can then iterate over the entities in model space or paper space via two ways:
1. by using the dwg.h data structures. Via dwg->object[0], which is of
type Dwg_Object_BLOCK_CONTROL,
and a custom void process_BLOCK_HEADER(Dwg_Object_Ref* ref):
Dwg_Object_BLOCK_CONTROL* block_control = dwg->block_control;
// first all entities in the model space
process_BLOCK_HEADER (dwg->header_vars.BLOCK_RECORD_MSPACE);
// then all entities in the blocks
for (i=0; i < block_control->num_entries; i++)
{
process_BLOCK_HEADER (block_control->entries[i]);
}
// and last all entities in the paper space
process_BLOCK_HEADER (dwg->header_vars.BLOCK_RECORD_PSPACE);
or 2. by using the API functions from dwg_api.h:
Dwg_Object_BLOCK_CONTROL* block_control = dwg_block_control(dwg);
process_BLOCK_HEADER (dwg_model_space_ref(dwg));
for (i=0; i < block_control->num_entries; i++)
{
process_BLOCK_HEADER (block_control->entries[i]);
}
process_BLOCK_HEADER (dwg_paper_space_ref(dwg));
and inside the process_BLOCK_HEADER function, you iterate over the entities
from the block_header via:
Dwg_Object* obj = get_first_owned_entity(ref->obj);
while (obj)
{
process_object(obj);
obj = get_next_owned_entity(ref->obj, obj);
}
where process_object checks the type of each entity under the
Dwg_Object* obj.
For each entity or object type (i.e. a non-graphical dwg object, also tables)
there also exist the simple and expensive dwg_getall_ENTITY and dwg_getall_OBJECT
functions:
int dwg_getall_ENTITY (Dwg_Object_Ref *block_header_ref) ¶Return a malloc’ed NULL-terminated array of all such entities for Model Space, Paper Space or an individual block.
int dwg_getall_OBJECT (Dwg_Data *dwg) ¶Return a malloc’ed NULL-terminated array of all such DWG objects.
The decoder is driven by the fields definition in the src/dwg.spec, which adds each field to the object. This is done in the src/decode.c or src/decode_r2007.c.
int dwg_decode_OBJECT (Bit_Chain *dat, Dwg_Object *obj) ¶Sets the fields for the object from the DWG bitstream.
Note: Pre-R13 DWG’s do contain all deleted entities, which e.g. where moved into a BLOCK. Those entities do have a type > 127. You need to filter them out by yourself, when processing the DWG.
Encoding DWG files, i.e. DWG write support, can be disabled via
./configure --disable-write. The default formats and only useful
ones are currently r1.1 - r2000. Experimentally work is ongoing for the r2004
format, which is also used for r2010, r2013, and r2018.
The r2007 format version is not covered yet.
The pre-r13 formats are much simpler and can be written, but need some
hand-holding and manual conversions when converting from newer formats still.
See src/in_dxf.c for a high-level usage example. The default codepage is Latin-1, 30.
The highest level function for encoding a bitstream to a file is
dwg_write_file, which dumps the dwg to a file.
int dwg_write_file (char *filename, Dwg_Data *dwg) ¶Open filename and write the dwg to it. Return 0 if successful.
See add api for:
Dwg_Data* dwg_add_Document (const Dwg_Version_Type version, ¶const int imperial, const int loglevel) Creates an initial template dwg structure in memory, suitable to be written to a DWG or DXF file, without any additional table records or entities. Creates ModelSpace, PaperSpace and most Tables and basic Dictionaries.
and how to add entities and objects from scratch.
Low level-functions:
int dwg_add_object (Dwg_Data *dwg) ¶Adds a new uninitialized object to the dwg->object[] array. Return 0 or -1 if successful, otherwise DWG_ERR_OUTOFMEM. -1 is the array was re-allocated.
Then for each object or entity type there is a
int dwg_setup_<OBJECT> (Dwg_Object *obj) ¶Initializes an object for the given OBJECT or ENTITY type, with all fields being zero’ed. This does not initialize the obj size, type, address, handlestream_size, bitsize fields.
The encoder is driven by the fields definition in the src/dwg.spec and the generated src/dynapi.c, which adds each field to the object. This is done by src/encode.c or any src/in_*.c import module.
int dwg_encode_<OBJECT> (Bit_Chain *dat, Dwg_Object *obj) ¶Encodes the DWG bitstream from the fields of the object.
The iterator is similar to above, but you want to encode all data structures, not just the entities. But note that you need many helper functions, such as the dynapi, to create all needed sections to store a DWG if you didn’t read a DWG into the right a Dwg_Data* dwg struct already. This is especially important when importing from DXF or from an earlier or later DWG version.
The add api functions are useful for CAD programs which want to write DWG. All the other API’s are mostly to convert from and to DWG, so the main structures and links already do exist. With the add api you can easily create an empty DWG from scratch, add table entries (into fixed Tables or variables Dictionaries), and add entities. To set more entity fields use the dynapi.
For each almost each entity and table exists a function at to add it, with arguments to initialize some fields as in the VBA object model. The other objects are either created automatically, or handled separately.
All BITCODE_T strings are encoded as UTF-8, as with the dynapi. See strings. Most names are copied, since most names are considered to be constant. If not, you need to free them by yourself. Exceptions are dxfname (there exists a separate dxfname_u variant), the VX name, which does not exists anymore since r2000.
A very simple example using the add API is the example program See dwgadd.
Dwg_Data dwg_add_Document (const Dwg_Version_Type version, const int imperial, const int loglevel)) ¶Creates an initial template dwg structure in memory, suitable to be written to a DWG or DXF file, without any additional table records or entities. Creates ModelSpace, PaperSpace and most Tables and basic Dictionaries.
When writing DWG, a version of R_2000 is recommended, only R_1_2 - R_2000 are supported yet. For DXF you can try all versions R_13 - R_2018.
For each OBJECT and ENTITY type there exists a specific dwg_add_<OBJECT> function, which takes the owner
and some default arguments. Entities are normally added to a block header, like modelspace,
paperspace or any block. Objects are normally added to the dwg, or to some other object or entity.
E.g.
Dwg_Entity_LINE *line = dwg_add_LINE (Dwg_Object_BLOCK_HEADER *modelspace, ¶dwg_point_3d *start_pt, dwg_point_3d *end_pt)
Dwg_Entity_TEXT* dwg_add_TEXT (Dwg_Object_BLOCK_HEADER *restrict blkhdr, const char* restrict text_value, const dwg_point_3d *restrict ins_pt, const double height) ¶Adds a TEXT entity to the ModelSpace, PaperSpace or a Block. Entity specific arguments are here the text, the point (as pointer to the struct of 3 doubles), and the text height.
Dwg_Object_LAYER *layer = dwg_add_LAYER (Dwg_Data *dwg, const char *name) ¶Adds a new layer the Layer Table, i.e. creates the new LAYER object, and adds it to LAYER_CONTROL object, the list of layers.
Names and strings are encoded as UTF-8 and will be translated to type BITCODE_T (i.e. versions specific TU or TV types, either UCS-2 unicode or single-byte codepage) internally, as with the dynapi. Only internally you will have to deal with 2 different DWG text representations: UCS-2 since r2007, single-byte before. see strings.
To understand the object model for the add API see some VBA Object model documentation, such as e.g. http://entercad.ru/acadauto.en/.
The new add API mostly handles the direct Dwg_Entity_ENTITY structs, not all the generic Dwg_Object structs.
Thus you can access the object specific fields directly, the common fields, not so easily.
The DWG Document consists of 3 basic entity containers ModelSpace, PaperSpace and Blocks, plus
Tables (Layers, Linetypes, ...), Dictionaries as generic replacements of Tables with a root Dictionary, the NOD ("Named Object Dictionary"), and more support objects and complex entity groups.
Helper functions:
dwg_add_u8_input (Dwg_Data *restrict dwg, const char *restrict u8str) ¶Convert UTF-8 strings to BITCODE_T fields. Returns a copy of the string. All external API’s only deal with UTF-8 strings.
The new dynapi replaced the old dwg_api functions to access each object field. The old dwg_api functions
were deprecated, and need to be re-enabled by defining CFLAGS="-DUSE_DEPRECATED_API".
See see Objects for an description of each object and its fields..
For each of header, entity, common or subclass there is a function to get and set the value of any type, or converted utf8 string.
bool dwg_dynapi_entity_value (void *entity, const char *dxfname, const char *fieldname, void *out, Dwg_DYNAPI_field *fp) ¶entity is of type dwg_ent_generic, that is the pointer to the object specific struct.
dxfname is the dxfname of the object, fieldname is the field or property name of the field to be read from,
*out the result pointer and the optional *fp is filled by the information for this field.
bool dwg_dynapi_common_value (void *entity, const char *fieldname, void *out, Dwg_DYNAPI_field *fp) ¶This accesses the common Dwg_Object_Object* or Dwg_Object_Entity* fields.
bool dwg_dynapi_header_value (void *dwg, const char *fieldname, void *out, Dwg_DYNAPI_field *fp) ¶This accesses the Header (or sometimes also called Database) fields.
bool dwg_dynapi_subclass_value (void *ptr, const char *subclass, const char *fieldname, void *out, Dwg_DYNAPI_field *fp) ¶This accesses a subclass, a structure within the object.
The utf8text functions convert version-specific text strings to UTF-8 strings. Internally the dwg stores strings as TU (unicode) or TV (single-byte codepage). The API treats all strings as UTF-8, as with JSON, DXF or the add API.
bool dwg_dynapi_entity_utf8text (void *entity, const char *dxfname, const char *fieldname, char *textp, int *isnewp, Dwg_DYNAPI_field *fp) ¶isnewp is set to 1 f the string is a fresh copy, for unicode strings.
bool dwg_dynapi_common_utf8text (void *entity, const char *fieldname, char *textp, int *isnewp, Dwg_DYNAPI_field *fp) ¶bool dwg_dynapi_header_utf8text (void *dwg, const char *fieldname, char *textp, int *isnewp, Dwg_DYNAPI_field *fp) ¶This accesses the Header (or sometimes also called Database) fields.
bool dwg_dynapi_subclass_utf8text (void *ptr, const char *subclass, const char *fieldname, char *textp, int *isnewp, Dwg_DYNAPI_field *fp) ¶This accesses a subclass, a structure within the object.
The setters don’t differentiate between common values and strings.
bool dwg_dynapi_entity_set_value (dwg_ent_generic *_obj, const char *fieldname, const void *value, const bool is_utf8) ¶Sets the ENTITY.fieldname to a value. A malloc’ed struct is passed by ptr, not by the content. A non-malloc’ed struct is set by content. Arrays or strings must be malloced before. We just set the new pointer, the old value will be freed. If is_utf8 is set, the given value is a UTF-8 string, and will be converted to TV or TU
bool dwg_dynapi_header_set_value (Dwg_Data *dwg, const char *fieldname, const void *value, const bool is_utf8) ¶bool dwg_dynapi_common_set_value (dwg_ent_generic *_obj, const char *fieldname, const void *value, const bool is_utf8) ¶See the sourcecode of the importers or programs for the usage of the API’s.
Internally the DWG consists of multiple different string formats, see Types.
The most important are BITCODE_TV (i.e. char*) encoded according to dwg->header.codepage,
and BITCODE_TU (i.e. wchar_t on Windows, UCS-2).
Externally most functions get and set strings as UTF-8, as in DXF or JSON.
Before r2007 DWG’s the TV and T strings are encoded in its codepage, and converted from and to their proper codepage to UTF-8 or \U+XXXX.
To encode unicode characters special \U+XXXX sequences are used, and pre-r2007 DXF MIF \M+nXXXX sequences, where n is one of the asian wide-character codepages 932 (Japanese), 950 (trad. Chinese), 949 (Korean Wansung), 1361 (Johab), and 936 (simplified Chinese).
On DWG’s r2007 and later most strings (T and TU) are encoded in the Microsoft specific two-byte UCS-2 Unicode encoding, without proper support for surrogate pairs and the upper planes (i.e. emojis).
Fixed TF strings are not encoded and have a length stored also. Normal strings are all zero-delimited. EED and XDATA strings do have a length though, but have length limitations.
Strings in DXF and JSON also have quoting rules for special characters, like \r, \n, \" and so on.
Transformations:
DWG to DWG: decode reads the T and TU strings in its natural format into the field. encode translate it to TV or TU. encode needs header.from_version and how it was read, from DWG or from an importer (in_dxf or in_json) or the add api (DWG_OPTS_IN).
DXF/JSON to DWG: in_dxf/json keeps the T and TU strings as TV. encode to <r2007 keeps it as TV, r2007+ translates it to TU. Unicode is encoded as \U+XXXX. It sets DWG_OPTS_IN.
DWG to DXF/JSON: decode keeps the T and TU strings as TV or TU. out_dxf/json translate them to TV or UTF-8 and quotes them via \U+XXXX.
add api to DWG/DXF: add reads strings as UTF-8, and encodes it from UTF-8 to TV or TU. (TU not yet, as we don’t encode r2004+ yet). add sets DWG_OPTS_IN.
We can write ASCII DXF files in various versions, with much more data than other free DWG libraries, but not as stable as the unfree Teigha library yet. AutoCAD ® fails to import some of our files still (~10% failure rate).
Options: --minimal (see dwg2dxf or dwgread) creates
only a short header with a ACADVER and HANDSEED element, and the
entities, without any subclass markers, reactors or handles.
Support for the different r1.x DXF format is not planned.
Reading DXF works for most objects. Converting a minimal DXF to DWG may fail, and needs some fixes.
We can almost write Binary DXF files in various versions.
Reading DXFB is under construction and un-tested.
We write to and read back from our own JSON format, which is a readable 1:1 mapping of the DWG structures, and carries much more information than the DXF format. The idea is to dump a DWG to JSON and filter/query or postprocess it with more powerful JSON query tools such as jq (https://stedolan.github.io/jq/), and optionally import it back in. See Programs: dwgfilter. JSON is much better structured than DXF.
The current first level objects are all the section names, like “HEADER”, “CLASSES”, “OBJECTS”. For more see the specs.
Note that for the versions before R13 we convert all tables to table control and record objects internally, so that we can use our iterators needed for DXF support. This does not reflect the internal DWG structure. See Tables.
dwgread supports writing to the GeoJSON format as specified at
http://geojson.org/geojson-spec.html. See dwgread with
the --fmt GeoJSON option.
We write in the RFC7946 format, the new GeoJSON format since 2016, which means smaller, less precision, and normalized polygons with proper right-hande rule orientation.
We write all coordinates as [x, y], not [y, x]. z-coordinates are optional, and only written if not 0.0. Colors are either written as palette index as integer if not 256 (ByLayer), or as TrueColor RGB hex string values for all r2004+ DWG’s.
Missing entities: No 3D entities, HATCH by definition. ELLIPSE, polyline bulges would need segmention into line segments. MLINE, SPLINE, MINSERT, SOLID, TRACE, RAY(?), XLINE(?)
Due to implementation quirks with ending commas in JSON, we mostly add an empty dummy feature at the very end, with null properties and null geometry.
LibreDWG is mostly a library, and as such collects error codes from
the highest level function down to the lowest level functions.
The error codes are sorted by severity, and only if the error exceeds
DWG_ERR_CRITICAL, i.e. DWG_ERR_CLASSESNOTFOUND, processing is stopped.
All error bitmasks are collected during read or write and returned at the end.
DWG_ERR_WRONGCRC ¶1
DWG_ERR_NOTYETSUPPORTED ¶2
DWG_ERR_UNHANDLEDCLASS ¶4
DWG_ERR_INVALIDTYPE ¶8
DWG_ERR_INVALIDHANDLE ¶16
DWG_ERR_INVALIDEED ¶32
DWG_ERR_VALUEOUTOFBOUNDS ¶64
DWG_ERR_CLASSESNOTFOUND ¶128 = DWG_ERR_CRITICAL
DWG_ERR_SECTIONNOTFOUND ¶256
DWG_ERR_PAGENOTFOUND ¶512
DWG_ERR_INTERNALERROR ¶1024
DWG_ERR_INVALIDDWG ¶2048
DWG_ERR_IOERROR ¶4096
DWG_ERR_OUTOFMEM ¶8192
Additionally, verbose warning and error messages are printed to stderr.
Unhandled class and Invalid type errors of objects are not severe. A DWG format can store a serialization of many third party classes and objects, and thus we will never be able read all possible types. Unknown types are just stored as binary blob without any DXF codes.
LibreDWG installs some binary programs to read or write DWG files.
This reads a DWG file, and optionally converts its content to some output formats: JSON, Minimal JSON, GeoJSON, DXF, DXFB (i.e. Binary DXF), SVG.
dwgread [OPTION]... DWGFILE
Options:
-v[0-9], –verbose [0-9] verbosity
-O fmt, –format fmt fmt: JSON, DXF, DXFB, minJSON, GeoJSON.
More planned formats: YAML, XML/OGR, GPX, SVG, PS.
-o outfile, –file outfile also defines the output fmt. Default: stdout
–help display this help and exit
–version output version information and exit
minJSON is minimized JSON, without whitespace.
Create a DWG from a given input file (see DXF, see Binary DXF, see JSON),
optionally via --as=rNNNN as another version.
For now can only create r1.2-r2000 DWG files.
Create a DXF from a given input file (DWG, see DXF, see Binary DXF, see JSON),
optionally via --as=rNNNN as another version. Experimental.
Supports the same options as dwg2dxf.
Converts DWG files to DXF, optionally via --as=rNNNN as another
version, an earlier or later version, or via -m or
--minimal as a minimal DXF version, skipping most headers vars,
classes, tables and objects.
--binary as a binary DXF file, with full precision, under construction.
The DXF files are created in the current directory and not overwritten, unless
the option --overwrite or -y is given.
Converts DXF (or Binary DXF) files to DWG, optionally via --as=rVER as another
version, an earlier or later version.
The DWG files are created in the current directory and not overwritten, unless
the option --overwrite or -y is given.
This program is experimental and AutoCAD ® may fail to import it. For now can only create r1.2-r2000 DWG. The default is writing as r2000.
Read and write the DWG, optionally via --as=rNNNN as another
version, an earlier or later version. The default is writing as r2000.
For now can only create r1.2-r2000 DWG.
Prints all layers in a DWG.
With -x or --extnames prints the extended displayed layer name with spaces,
not the internally stored old-style name with _ instead.
Only relevant with old r13 and r14 DWGs, after that layers are always stored in the extended format.
With -f or --flags also the status of frown, on/off and locked.
With --on only the visible layers, which are on and not frozen.
You can get the same effect via this json filter:
dwgfilter '.OBJECTS[]' example.dwg | \
grep -A22 '"object": "LAYER"' | grep name
Search regex pattern in all text values in a list of DWGs. dwggrep uses PCRE.
With -i searches case-insensitive.
With -c prints only the count of found texts.
With -h or --no-filename does not print the filename.
With --type NAME search only NAME entities or objects.
With --dxf NUM search only in DXF group NUM fields.
With --text searches only TEXT-like entities: TEXT, MTEXT, ATTRIB, ATTDEF.
Search and modify a single DWG file via jq, using the powerful
JQ query expression language on a temporary json file. See man jq.
With -i replaces the DWG in-place. This only makes sense with an JQ expression which changes values.
Convert a DWG to a limited SVG. All paperspace or modelspace enties of type: TEXT, LINE, CIRCLE, ARC, POLYLINE_2D, LWPOLYLINE, INSERT, ELLIPSE (unrotated), SOLID, 3DFACE, RAY, XLINE.
With -m or --mspace all paper-space entities are
ignored, and only model-space is printed. The default is to print all
paper-space entities. But if there are none, print all model-space
entities instead.
Limitations: Many other graphical entities and some properties are still missing.
Convert a DWG to a very limited Postscript file. All paperspace and modelspace entities of type LINE, POLYLINE_2D, LWPOLYLINE, ARC and CIRCLE.
This requires installation of pslib http://pslib.sourceforge.net/doc/pslib.html.
Note that the graphical representation for PS and SVG output is severely lacking, block references (insert entities) are not yet exploded, UCS and paper space transformations per entity are not yet done.
Planned is dwgplot, via GNU Plotutils https://www.gnu.org/software/plotutils/, to replace dwg2SVG and dwg2ps. This supports much more bitmap and vector formats.
There are also some more examples in the source distribution:
loads a DWG and adds some entities.
converts a DWG to SVG similar to dwg2SVG, but via the dwg_api.h only. The graphical representation for PS and SVG output is severely lacking, block references (insert entities) are not yet exploded , UCS and paper space transformations per entity are not yet done.
lists the not yet reverse-engineered blobs from our examples files, and is the framework to guess the field layout for these. It is optionally using picat (http://picat-lang.org/) to solve some of the field-packing problems.
afl++ fuzzing frontend, to test and debug various fast shared-memory options for afl-clang-fast,
with the following runtime options: -indxf, -injson, -rw, -dwg, -dxf, -dxfb, -json, -geojson. All other output formats, like BMP, SVG, PS need to be fuzzed via their programs, which is the recommended way.
The now default and fastest method INMEM does not need the 2nd file argument @@, the 2nd method STDIN neither.
See also https://github.com/LibreDWG/libredwg-fuzz for our fuzzing setup to test new fuzzing campaigns automatically and find regressions.
is the easiest way to create DWG’s (or DXF, JSON) from scratch or add entities to an existing DWG.
It accepts a very simple file with commands to create entities or objects and set its properties.
See man 1 dwgadd and man 5 dwgadd.
LibreDWG generates library bindings to python and perl5 via swig. These can be quite huge, and it is recommended to use ccache. You can easily add bindings to other swig-supported languages, like Go, C#, ruby, php, D, lua, tcl, common lisp, ocaml, or others by yourself. Patches accepted.
Bindings for gambas (which looks very close to VBA) are at GitHub and will soon be added to gambas3 as gb.dwg component. This is in development and about 80% finished.
See the separate refman manual (in pdf or html format, the pdf has ~1800 pages) for a detailed API description, or see the relevant dwg.h, dwg_api.h or the *.spec files.
For reference you might also want to check the public DXF reference manuals, the VBA object model and the ODA OpenDesign_Specification_for_dwg_files.pdf.
To report bugs or suggest enhancements for GNU LibreDWG, please “submit a bug” at Savannah or send electronic mail to libredwg@gnu.org. (If you use the web interface, you don’t need to also send email, since that is done automatically.) Issues and pull requests at the github mirror are also accepted.
For bug reports, please include enough information for the maintainers to reproduce the problem. Generally speaking, that means:
configure other than specifying
installation directories.
When in doubt whether something is needed or not, include it. It’s better to include too much than to leave out something important.
Patches are welcome; if possible, please make them with ‘git format-patch’ and include ChangeLog entries (see Change Log in The GNU Emacs Manual). Please follow the existing GNU coding conventions. For patches longer than 15 lines we need your copyright assignment to the FSF clerk. See CONTRIBUTING in the source distribution.

A “Secondary Section” is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document’s overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.
The “Invariant Sections” are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections.

The “Cover Texts” are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.
A “Transparent” copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not “Transparent” is called “Opaque”.
Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification.

Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.
The “Title Page” means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, “Title Page” means the text near the most prominent appearance of the work’s title, preceding the beginning of the body of the text.
The “publisher” means any person or entity that distributes copies of the Document to the public.
A section “Entitled XYZ” means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language.

You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.
You may also lend copies, under the same conditions stated above, and you may publicly display copies.
If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document’s license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.
If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.
It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.
You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:
If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version’s license notice. These titles must be distinct from any other section titles.
You may add a section Entitled “Endorsements”, provided it contains nothing but endorsements of your Modified Version by various parties—for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.
You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.
You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections Entitled “History” in the various original documents, forming one section Entitled “History”; likewise combine any sections Entitled “Acknowledgements”, and any sections Entitled “Dedications”. You must delete all sections Entitled “Endorsements.”
You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.
You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.
A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an “aggregate” if the copyright resulting from the compilation is not used to limit the legal rights of the compilation’s users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document’s Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.
Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.
If a section in the Document is Entitled “Acknowledgements”, “Dedications”, or “History”, the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.
You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License.
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it.
The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.
Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License “or any later version” applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy’s public statement of acceptance of a version permanently authorizes you to choose that version for the Document.
“Massive Multiauthor Collaboration Site” (or “MMC Site”) means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A “Massive Multiauthor Collaboration” (or “MMC”) contained in the site means any set of copyrightable works thus published on the MMC site.
“CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization.
“Incorporate” means to publish or republish a Document, in whole or in part, as part of another Document.
An MMC is “eligible for relicensing” if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008.
The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing.
To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:
Copyright (C) year your name. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled ``GNU Free Documentation License''.
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the “with…Texts.” line with this:
with the Invariant Sections being list their titles, with
the Front-Cover Texts being list, and with the Back-Cover Texts
being list.
If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation.
If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
