Hi Michael...

I have two questions :
1. I want : rotate scroll button forward = zoom out, rotate scroll backward = zoom in.
2. Is there a way to change the moi rotate button ? I want : to rotate model is by hold down scroll button then move the mouse.

Basically I am solidworks user, so I want the moi zoom & rotate feature same as solidworks.
I have used solidworks, AutoCAD, and another 3D software. I think the zoom & rotate that solidworks have is the best. Very easy.

I have tried to change the moi setting under rotate/zoom/pan. But not work.
