(...) I was just pointing out that the clippability of transparent surfaces is a feature of the rendering program, and shouldn't be assumed in the description language. Steve (25 years ago, 8-Oct-99, to lugnet.cad.dev)

(...) Checking the order of points in a file should not depend on checking the inversion or subfiles for the file. That's why we've been talking about the 0 FACE UNKNOWN -- so parts of files can be fixed, even if the entire file can't be addressed. (...) (25 years ago, 8-Oct-99, to lugnet.cad.dev)

Gary Williams wrote in message ... (...) "...not dependent on any other file..." Well, I hope you agree that files depend on the inside/outside-definition of subfiles? Otherwise a file wouldn't know whether or not to use the INVERT. /Lars (25 years ago, 8-Oct-99, to lugnet.cad.dev)

Hello all We have another fine naming issue on our hand, which is always good for a lively discussion tread :-) The issue is about the parts from the group "Train Track 4.5V". I believe two different types are known here: 1- the oldest "Blue" type (...) (25 years ago, 8-Oct-99, to lugnet.cad.dev)
