Object that rotates around another but not on itself Noob question here. When rotating a parent, I'd like to fix the child's orientation in space. I put a video on youtube linked below where the child cube's red face remains facing the parent(what I don't want,) and the second 2.5 seconds shows the red face remaining fixed(what I do want.)

The problem is- I had to rotate the child -360 degrees when I rotated the parent +360 degrees to accomplish this. It seems clunky. Is there a simpler way to accomplish this? I tried rotation lock and didn't have success. Sorry, it's an embarrassingly amateurish question. Any help would be greatly appreciated.

One solution is to parent object B to object A, give a Limit Rotation constraint to object B, and limit the constraint on the Z axis: Object B will rotate around A but won't rotate on itself.

Another solution, suggested by Frederik Steinmetz, is to not parent B to A, to parent an empty to A, and give B a Copy Location constraint with the empty as Target.
