I have a bone that needs to be snapped to a cursor selection, but with a constraint. I understand how to select the tip of a bone and then SHIFT+S and then select Selected to Cursor to move the bone tip to the cursor.
My question is, I would like to press X before snapping so I can force the bone to move only along the X-Axis as the degree of freedom. In other words, use the "X" component of the 3D cursor while using the Y-Z components of the root of the bone. How do you do this? Does this make sense?
I see there are some links on the subject, but I don't know what they are talking about to follow along.
