(...) Actually, if you use conditional lines that follow the red tangent lines, as in Travis' diagram, then you want them to overlap. You get partial coverage from each of them that adds up to the total coverage you'd get from the original style of (...) (20 years ago, 4-Nov-04, to lugnet.cad.dat.parts.primitives)

When using the 2-4cyli primitive I noticed one conditional line missing, so I compared all different cyli primitives.

(...) From the way Steve explained it, it sounds like stug4 would be a 4x4 square, not a 2x2 square, in which case going from stugN to stugN+1 actually does give you another 2N+1 studs. When you think about it, by your reasoning, you'd never (...) (20 years ago, 25-Oct-04, to lugnet.cad.dat.parts.primitives)

Since I haven't authored any parts, I'm not going to go into this too deeply, but I think that square groups is a good idea. One minor note. Going from one group size to the next gives you 2 * sqrt(N) + 1 new studs, not 2N + 1. --Travis (20 years ago, 25-Oct-04, to lugnet.cad.dat.parts.primitives)

(...) I think they are fine the way they are. The basic reason is size. The bushlocks are 20 LDU in diameter. 48-segment primitives are not needed until you get to 80 LDU diameter curves.
