Calculate Angles (in LDCad)

[N. W. Perry]

I just managed to learn Ldcad in the past few month. Switching from studio. Cable routing function is so useful. However I couldn’t figure out how to measure angle in a non XY XZ OR YZ plane. For instance of my parts was in a plane with both yaw and pitch. It only measuring angles with respect to horizontal, vertical planes. 
Also I couldn’t find a way to rotate part in such a way with an axis with both pitch and yaw angle. Is there a script for that? 
Thanks

To measure angles from a rotated part, select it and press "O" or click ABS in the editing compass to toggle it to REL. That sets the grid to that of the rotated part instead of the base XYZ axes.

To rotate around an axis besides XYZ, select the part(s) and then hit ALT-R to bring up the rotation dialog. The drop-down menu gives several options, including rotating around a custom vector or a given matrix. If you've toggled to a REL grid, these options will work starting from there, unless you check the box for Absolute rotation.
