| (...) Travis, I understand 3D rotation matricies enough to know that they let you rotate around any axis, but I think MLCad's GUI only lets you rotate about, X, Y, or Z, because of limitations of its user interface. Michael has meta-commands for (...) (20 years ago, 8-Jun-05, to lugnet.cad.mlcad)

Imagin you had an axle that is at 45 degrees in the XY plane, and you have a biped leg you want to rotate around the (...) (20 years ago, 7-Jun-05, to lugnet.cad.mlcad)
