Ahoy Boat, I am not sure why you are at sea with a pea green mouse (!?)....constrain up...not that I am aware of, but you can:
- middle mouse double click on a straight edge- including from a sketch and temp axis -to rotate you model about that.
failing that to help you can get about the SW world:
-set up named views of your own to quickly revisit favourite places - get you desired view in the window, hit the space bar and pick the first icon, enter a name...pin the menu to access all the time.
-or you could use the arrow keys for pure rotation relative to the screen view. (Shift arrows for rot 90 deg at a time).
-or you use the std views toolbar to realign to a known point like Front or Top if you get lost - you can re-orientate those relative to your model too if you wish - space bar, second icon. (someone here wrote a macro to give an isometric view set like the std views if that is more useful.)
anchors away :o) neil
