I know this is an old discussion, but I really like Steve's idea of
meta-statements to control this.
What would be really cool is to have all the primitives and parts in the parts
library have the meta-statements that simply turn smooth triangles on and off.
This way we would not need a heuristic.
It is probably a *huge* effort, but we could run each part in the library (and
primitives) through a heuristic and then review each part to see if we want to
override the heuristics. This is probably really nieve, due to the amount of
work, but it is the optimal solution.

| (...) Actually the meta-statements are probably unnecessary because all the information already exists in the parts in the form of type 2 and type 5 lines. Type 2 lines indicate a hard edge and type 5 lines (or the absence of type 2 lines) indicate (...) (22 years ago, 11-Nov-02, to lugnet.cad.ray)
