| | | To make rotation work like you want, you have to move the group to the origin of the MLCAD space, rotate the group, then relocate the group to where it started. Kevin (...) figuring (...) (22 years ago, 20-Sep-02, to lugnet.cad.dev)

| | | | (...) Lets try it with vectors. Calculate the vector V from the arm origin to the hand origin. Rotate this vector about the arm origin (by angle A) to generate vector W. Subtract V from W to generate displacement vector X. Add the displacement (...) (22 years ago, 20-Sep-02, to lugnet.cad.dev)

| | | | (...) Actually, if I remember right, the Minifig Modeler in LDAO uses LDLite statements for placement and rotation. Of course, it's been awhile since I was in that code, so I could be hallucinating... 0 TRANSLATE <to end of arm> 0 ROTATE <wrist into (...) (22 years ago, 26-Sep-02, to lugnet.cad.dev)
