 | | Symmetries other than 16 and 48?

What is the general way of handling parts/primitives that have rotational symmetries other than 16 and 48? I am currently looking at reworking 73071 (the old Technic Differential), which has a rotational symmetry of 28, and 3649 (Technic Gear 40 (...) (21 years ago, 22-May-03, to lugnet.cad.dev)

Thanks Don and Paul. I think that pretty much answers my questions for now (but no doubt I will have more later). Now to go fix some of my primitives and parts... --Lance-- (21 years ago, 22-May-03, to lugnet.cad.dev)

(...) I'll drop a few quick secrets on how I use conditional lines. First off, I use LDAO and L3lab for the largest amount of part modeling. Usually check occasionally with LDview and Ldraw. So if you are using MLCad, and do not have LDAO, I would (...) (21 years ago, 22-May-03, to lugnet.cad.dev)

Neat stuff. I was curious if one could infer what TLC's internal data formats might be with this info from the Dekstop Engineering article. The link to Unigraphics gets redirected to EDS. It seems they were acquired since the article was written. (...) (21 years ago, 22-May-03, to lugnet.cad)

In reading past posts, it seems that putting in optional lines is encouraged, but I have not been able to find any information on the proper way of using them.
