It used to be (and still can be) that you could only apply constraints to objects after they were created. One problem that we frequently ran into especially using the “auto constrain” tool was “Over-Constraining” these objects.
New in 2011 is the INFER toggle on the status bar (drafting settings buttons).
Turn this toggle on and start drafting and don’t worry about the constraints. they will take care of themselves.
I ‘ve tried it on isometric dimension and not work but on align dimension it work
What do you think?
