First of all, I like the idea of a unit capped cylinder. The stud could then be changed to a reference to the new primitive. We could use x-ycylc as the filenames and call the primitive Cylinder Capped. This would be consistent with the existing 1-4cyls (Cylinder Sloped) primitive.

One concern about capped cylinders is that they would lead more multiples of cylinders - single-capped cylinders, double-capped cylinders, 1/4 capped cylinders, 2/4 capped cylinders, Hi-res 3/8 double-capped cylinders, etc. etc. And every single capped cylinder will actually be a compound primitive -- i.e., a composition of one or more cylinder, disc, and edge primitives.

While capped cylinders would be useful, I don’t think they would be worth the overhead.

I agree with you in all points.

But if I see that also you are thinking that capped cylinders are useful maybe there is somebody out who can write a prog for that. I have tried something similar in the past and was not very happy with the handling. You can found that on my webside (under LDraw / Programme / LDraw - Tools) as excel file “cylindercut.xls” and “circlecut.xls”.
