 | | New Primitive - 1-8t0102 1/8 torus, 1-inner Radius, 2-outer radius [DAT]

Hello, Here is a new proposed primitive. It has an inner radius of 1 ldu, and an outer radius of 2 ldu. I have a spreadsheet that made this, so I can generate just about any size needed for a standard 16 point circle. I have been working on a (...)

(...) Hi everyone, Here is another Torus file updated to include the POV code to render a nice looking 1/8 torus. I believe this file was used on a chain piece that someone was working on. I have several other Torus dat files created, so if one is (...) (24 years ago, 28-Dec-00, to lugnet.cad.dat.parts.primitives)

(...) Because I was thinking that each section covered 90-degrees of the major circle. Otherwise, they'd be named 16t*0301.dat, since each is 1/16 of a complete torus.

Does anyone have anything to say or add about the torus primitives? I have a few parts in process that use parts of a torus that can be finished up once we decide on a format and file name structure. Any comments are welcome. Some of the parts can (...) (23 years ago, 9-Feb-01, to lugnet.cad.dat.parts.primitives)
