Actually didn't find anything about this on the forum. Sooo, is this a thing? In particular I'm interested in coding a rail joint which needs to be a weird hybrid of semi-circular sections and straight lines. By rail I mean that an anchor point is confined to a pre-defined "rail" (think roller coaster). This is for some wall climbing type code.
Anyway, is there any documented way to create a custom joint, or at least some specifications? Thanks!
