The !polycheck Command: Check Polygon
Syntax: !polycheck [layer ...]
This will apply the reentrancy test on all polygons (no arguments) or
polygons on the layers given in the current cell. Polygons that do
not pass are selected.
For certain conditions, !polycheck will repair the error
silently. The following conditions are repairable:
- If a reentrancy condition can be avoided by moving a vertex by
one database unit, the vertex will be moved.
- If a ``needle'' vertex is found, it will be removed. A needle
vertex is a vertex where the path doubles back on itself.
