Controlling location of Rotation axes.
When I create a 3d object and then just use the mouse to rotate the object, it happens quote often that the objet rotates out of visibility. I do not understand how the axis of rotation (for rotation with the mouse) is defined. Can this be controlled?
Let us say that I create a unit cobe and want all the rotations to have their center in the center of the cube. How can i do this?
