I have a model that does not seem to want to snap to the floor. It will snap to about an inch or two above the ground. I suspect that it has something to do with the bounding box of the wheel model, so I tried to rotate the wheel a bit to fix it. When I selected the wheel, I centered the pivot point on the wheel and it moved to the center as expected. However, when I typed in "0" for the value that would rotate it to the correct position, it rotated around a completely different axis and moved away from where it should be. Has anyone else had this problem, either with bounding boxes not allowing round objects to ground or objects not pivoting around the right point?
