I believe some of you used Google Sketchup. On first try their camera is a a little bit confusing.
But after only few hours you relize that is best possible way for camera controls with mouse.
I try tons of different 3D programs from SolidWorks, Rhino, Maya, 3DS Max, AutoCAD... and find it easiest.
Orbiting is much smother and slower there.
At least we need much more control over camera control settings.
Here is few suggestion:
1- Make camera control settings tab in settings
2- Give us option to customize which button (on mouse or keyboard) to use for Orbit, Pan
3- Option to chose what type of zoom we want (mouse wheel, keyboard buttons or something else)
4- Option to tune sensitivity for Orbit and Zoom
5- Checkbox for Orbiting around point where is mouse click (if you click on left part of object you rotate camera around that part!)
Then you will be able to remove this 'advertisment' for other programs with these presets for camera profiles 🙂
