I noticed that V6 brings back an interesting option in “Rhino Options/View/Rotate” witch is “Classic V2 Style Rotate Relative to View”.
Personnally, I really appreciate how the “Rotate Around World Axes” works. The way I understand it is that the camera rotates around de “Z” world axe. Unless I missed something, there is no way to ask to rotate around another axis. This option would be very usefull when we need to work around an imported model from another software where the user did not use the “Z” axis as his vertical axis. I know we can set the view option to “Rotate Relative to View” but that means we lose the feeling of “Rotate Around World Axes” if we like it. The other option is to rotate the object so it has the “Z” as the vertical axis but sometimes it creates confusion and potential mistake when models are moved.
Having the option to “Rotate Around World Axes” and being able to choose the axis we want would give the best of both world (no model displacement and the rotation we want).
