1. Why we cann't swap coordinate system to be Y-up or Z-up any time we want?
Why we need to exit program to enable so?
Why can't we allow different sessions can have their own coordinate system setup?
2. Contruction plan still have the view spinning follows the original coordinate system
Why can't they spin by their own coordinate system?
For construction plan, they should have their own Y-up or Z-up to be chosed
We have a HOME for go back to original orientation, this wont confuse users!
