(...) It's me... (...) I have had a few emails with the Parts Tracker admin's lately to discuss the creation of primitives. I was INCORRECTLY using the rounding method that rounded only the final results. Like this; round( r* sin( Angle ), 4). The (...) (21 years ago, 11-Jun-03, to lugnet.cad)

(...) Sounds good. Make sure your generator is using spaces and not tabs. I have not checked to see how the original Ldraw responds to tabs as number seperators. Paul (21 years ago, 11-Jun-03, to lugnet.cad)

(...) I think for parts, you can use either method -- because, as the part author, you are responsible for making all the vertices match up. The point with this discussion, is to support using primitives in parts by creating the primitives in a way (...) (21 years ago, 21-Jun-03, to lugnet.cad)
