For all objects in the model area, there is no full possibility of rotation in this working space. The are lot of limitations.
Example (shaded mode) - for this standard case is:
- the rotation via X-axis not possible (blocked)
- the rotation via Y-axis limited to +/-90° only
- only the rotation via Z-axis possible in the full range

It doesn't matter if I use rotation via SHIFT+Mouse, 3Dorbit, ...
The free rotation in each axis is the BASIC function of all other 3D CAD (Inventor, SolidWorks, Catia,...).
We don't want to pay for a 2,5D CAD license.
