<H3>Summary:</H3>
|
||
|
|
<BLOCKQUOTE>
|
||
|
|
The <B>polygon</B> command allows generation of polygons on the
|
||
|
|
layout from the command line, similarly to the <B>wire segment</B>
|
||
|
|
command. The <B>polygon</B> command automatically generates the
|
||
|
|
proper tile geometry for the polygon as specified by vertices.
|
||
|
|
Vertex points are pairs of X Y coordinates, and may take any
|
||
|
|
dimensional value (default lambda, but may be internal units or
|
||
|
|
metric units). Note that polygons should be convex; the tile
|
||
|
|
generation algorithm is not guaranteed to work with non-convex
|
||
|
|
geometries. <P>
|
||
|
|
|
||
|
|
While simple non-Manhattan structures (triangles) can be generated
|
||
|
|
with the "splitpaint" and "spliterase" commands using macros, there
|
||
|
|
is no convenient interactive method for generating complex polygon
|
||
|
|
geometry. The <B>polygon</B> command is best used in scripts to
|
||
|
|
create specific patterns based on known geometry.
