OK, what I mean by this is can you create a visibility state(s) and NOT have the ability to change them manually in the drawing? I tried making the visibility state marker invisible in current state, but that didnt work. Where I am going with this, is I would like to duplicate some ADT functionallity where you have a 2D view in plan, and it switches to a 3d view when your viewpoint moves from 0,0,1.
Any ideas?
