Hi Massimo,
Only 4 buttons on my Cadman: Zoom to Fit, Wireframe, and 2 held in reserve for 'on-the-fly' rotation points :wink: I also have about 30 macros on the Belkin Speedpad.
Speaking of the 3D Connexion gizmos, I discovered that they do Pan an Alibre Drawing, it's just that the sensitivity set for Panning is orders of magnitude less than that for Zooming, so it's hardly noticeable. If you're patient enough you can see it creep across... Similar problem to the Panning of 'large' objects in Part space.
