The LSC just ratified and made changes to the
File Format Restrictions for Official
Parts. A section was added to specify colinearity and convexity restrictions
for triangle and quads:
Colinear Tolerance/Concave Quads
A quad (line type 4) or triangle (line type 3) must not have aligned vertices.
Additionally, quads should always be convex. (Concave quads should be split into
two triangles.) To avoid concave quads, as well as aligned vertices in triangles
and quads, every interior angle in a quad or triangle must not be greater than
179.9 degrees or smaller than 0.025 degrees. (Note: Parts already in the library
or certified on the tracker are not to be re-submitted just to fix any colinear
violations.)
