I have two questions:
I have two objects that are part of a camera housing that should be perfectly aligned and vertical. I accidentally rotated them to an unknown angle at the same time, so they are still aligned with each other as they should be, but when I shift+select them, the gumball is oriented to the world (not aligned with the objects’ tilted angle), and I don’t know exactly how far I need to rotate them to get them back to vertical. What is the best way to perfectly re-orient them to both be perfectly vertical?
In a related question, I have a full camera model with lenses, housing, etc. that mounts to a ball joint where the camera pivots. Is there a way to permanently set the axis of rotation of that group of objects on the center of the ball joint, so that I can pivot the whole camera as a unit to show it in different orientations, and then be able to go back and reset the tilt to vertical?
Thanks in advance for your help.
