(...) I like the 16 triangles better. It makes it easier to split the primitive into sections if I need to. (22 years ago, 13-Jul-02, to lugnet.cad.dat.parts.primitives)

(...) The motivation is that 4-4disc is used by "stud" primitive. So I expect a small speed improvement (still to be demonstrated). Damien (22 years ago, 13-Jul-02, to lugnet.cad.dat.parts.primitives)

Hi Orion and Franklin, (...) Be sure I carefully consider opposition. I would not submit these primitives against general consent. I have made empirical measurements. I have found about 2 percent speed increase when model has many studs (yellow (...) (22 years ago, 14-Jul-02, to lugnet.cad.dat.parts.primitives)
