Perry Wrote: I don't suppose this is related to the update, but I couldn't get anything with a stud to snap to either the open end of 4349.dat or the center hole in the back of 4598.dat. Both those parts do have cylinder snap metas in those locations, but they don't seem to recognize a simple stud-to-antistud connection. (The 4598 has what you've called a "barrel snap"—what's that?)
The horn info uses 6.5 radius so studs (R=6) won't match. I'm not entirely sure why I gave ithat ratio as I know the reallife use of the part. Probably because the drawn shape doesn't seem to accept a stud (no bevel for it).
I'll improve the info to ignore the shape and accept it anyway.
barrel snap is for the 2x2 barrel / container parts which snap to 2x2 anti studs but don't have actual studs them selves, e.g. 2489
