I’d like to second the request for customizable navigation gestures. And not just “make Shapr3d work like program XXX.” Let me assign an arbitrary modifier key and mouse button for each pan, rotate, and zoom motion.
Reason for me is that I have a disability in my hand that prevents me from using a traditional mouse. I have an old iGesture trackpad (which they don’t make anymore) that is wonderful at letting me do most things. But it’s limited in that the only type of drag motion it can emulate is a left mouse button held down drag. All of the CAD program presets require either a right button held down or a middle button held down kind of drag which this device can’t do.
So please offer a choice of something like: Option left button drag to pan. Control left button drag to rotate. Command left button drag to zoom.
