If there are many CATIA style rotation fans, please at least make it switchable in options to 'NX' mode Point: One point is created for visualise the point rotation axis: red X, green Y, blue Z. CATIA works just like that: when object is fitted to view, camera rotates just like in example 1, but when i move it, it pivots about center of screen.
