The file  2741c.dat could be a base for a new sort of tore primitive. It has 24 segments for the complete circle and its
better for large tores like the one used in this part.

Any comments ?

note: I've made toroidal bits before, using an approach similar to
2741c.dat, except I built 2741c.dat out of a 4-4cyli.dat and some
2-4cyls.dat.

The reason we had the recent discussions about standardized torus p-files
was so it would be easy to add (and utilize) more torus files in the
future.

2741c.dat could be cast into the torus standard.  You would need to split
2741c.dat into inside and outside files, and rescale it so the major circle
axis = 1.  I think the file names would be:

T24I1363.DAT
T24O1363.DAT

More generally, the reason we stick with 16- and 48-segment circular
objects is to make it easier for everyone to work with the primitives, to
integrate them with angular surfaces.

Also, looking at your file in L3Lab, I don't think the 48-segment
primitives would be too detailed.

  Hi-Res primitives : was - [Idea] New kind of tore for large diameter
 
On the subject of Hi-Res primitives, I have been developing several lately. Should we have a "new" posting group so that they do not get mistakenly downloaded as "16's". So far the "48's" primitves I have made are, 1-4con1.dat thru 1-4con10.dat (...) (23 years ago, 21-Jul-01, to lugnet.cad.dat.parts.primitives)
