Drag handle control; points and csys (?)
I need to know if there is a way to manage the active dimension when dragging a csys or datum point.
To clarify, I need to drag a point around that is spherically bound to a Csys.
I need Z to remain constant and drag only in theta or axis angle.
This is similar with a cylindrical Csys...
You only get one drag handle that manages 3 associated dimensions.
How do I switch which of the 3 dimensions are affected while dragging?
(this is my current use case but even a cartecian point presents this challenge)
