| | | | | | (...) Well, I wasn't going to compile an "über-list" of all the oddly angled parts available, just the ones I've had some problems with determining the angle of. In fact, I think I'll post the list here, as it isn't too long: 2904 Pivot angle: 15 (...) (25 years ago, 15-Jul-99, to lugnet.cad.dev)

| | | | (...) I'm probably stating the obvious here, but... Please also include the coordinates for the pivot as well as the angle. You may now freely deduce how many times I've burned myself on this simple concept! :-, Cheers, - jsproat (25 years ago, 14-Jul-99, to lugnet.cad.dev)

| | | | (...) Okay. In order to pivot a piece, you need two pieces of information: the *angle* of rotation, and the *axis* of rotation. Given one, it's a little work to figure out the other. Cheers, - jsproat (25 years ago, 15-Jul-99, to lugnet.cad.dev)

| | | | | | Re: Parts with odd angles —Jeremy H. Sproat
|
| | | | | (...) Note that the angle and axis of rotation can be wrapped up nicely in a LDraw matrix -- suppose we supply this data as a preformatted matrix? Thus, a Technic Motorcycle Pivot Rotation Guide would be an LDraw line with the proper rotation matrix (...) (25 years ago, 15-Jul-99, to lugnet.cad.dev)

| | | | | | Re: Parts with odd angles —Jeremy H. Sproat

| | | | (...) Gotcha. (...) Sure, but there are several non-hinged pieces that do have an axis of rotation (or pivoting, anyway), the ones coming to mind are: 2904.DAT Technic Motorcycle Pivot 2342.DAT Space Control Panel (needs work) Also, tons of pieces, (...)
