 | | BFC revisited
|
| I'm looking for a model file that utilizes BFC-certified parts to test backface culling in the CAD application I'm developing. Unfortunately, as near as I can tell, only 13 part files have a BFC-related comment, and on top of that, they're not (...) (23 years ago, 16-Aug-01, to lugnet.cad.dev)

| I have printed the bfcspec file for review. Hopefully I will get a response back to you. I have been using BFC in most all my new parts for the last six months or so. Please send me the BFC compliant primitives, so that I can be sure I am using them (...) (23 years ago, 17-Aug-01, to lugnet.cad.dev)
