I found this thread looking for a way to mirror an object’s axis as well as its geometry. I’m in a similar position of having a robot. I modeled any symmetrical objects using the Symmetry object – it worked very well for me. I tried the Mocca method as an experiment, and that also worked.

The only problem I’m having is mirroring the object axis. For example, my robot model has hands which are somewhat complex (for me) and I’ve rigged them using FK (not IK). Each part, such as pieces of the fingers, have their own rotation and their XYZ axes are aligned accordingly. None of the methods described actually mirror the axes, so if the left hand has a rotation of 20x, 35y, 15z, the mirrored copy does not have the equivalent reflected angles. I can get the axes to translated across the YZ plane, but not mirror themselves. I tried just placing a negative sign in front of the angles in the rotation column of the coordinate manager, but that doesn’t yield the proper result.

So, in addition to simply mirroring geometry, how can the object axis also be TRULY mirrored and not just translated across a mirroring plane?
