The problem I'm having is when the center is not rotated the same as the plane I need to duplicate on. You can no longer duplicate multiple with additive rotation. I can get around this by picking a reference plane then opening it's properties and copying all the rotation and position coordinates to the corresponding "center" transform for the object I want to pivot/rotate. This is a huge pain in the ass!
Please someone tell me there is an easier way to do this. All I basically want is a "match all transforms to reference plane" button. This would also help when extracting polygons from a mesh. The new extracted mesh just ignores it's former parents transforms and returns the center to 0,0,0 with 0,0,0 rotation.
I should also say that this is really only a problem for me when trying to duplicate multiple objects. Otherwise "ref" and "plane" modes work just fine.
God I hope I'm making some kind of sense.
