Added Stellation Pattern 1c. It has double lines and areas marked for cutting out so that resulting pattern can be used as a template for drawing.
The template should produce acceptable results for papercuts. Where precision is needed, such a template should not be used, but rather the drawing should be transferred using graphite paper.
Stellation Pattern 1c includes
bridges to prevent the pattern from falling out of the
surrounding material. I recommend the use of heavy paper. It might be
possible to use light Bristol board, but cutting out might be difficult
and the blades would dull quickly.
I've had poor results using thick Bristol board for this purpose; it was very difficult to cut out. I've had acceptable results using fairly heavy watercolor paper, however, it's soft and tends to dull the blades quickly. Paper will, of course, eventually wear out.
There are a couple of kinds of plastic available that might be suitable. However, I have only seen them in a catalogue for model-building supplies and have never seen the actual material.
Added the macro generate_star to the file stlltns.lmc. It's used to generate Stellation Pattern 1 and 1a. The latter version has double center lines.
The file stlltns.lmc (used by stlltn03.ldf) contains the definition of the macro generate_pattern, which can be used to create various patterns similar to the image above, depending on the parameters passed to it. These parameters determine the number and shape of the parallelograms and whether the outer circle of parallelograms is drawn.
Additional parameters could be defined to influence other features of the pattern, such as the relative distance between the parallelograms in each set of concentric parallelograms. The code could also be changed to make it possible to have quadrilaterals that aren't parallelograms, or other shapes.
