How to change dimensions in ZW3D ?

Hey, I have a question. I draw a rectangle (1), then I make dimension on its side (2) and then I change it (3). But when I change dimension length is the same as before.

Colin, thanks, but it was something else. It started to work when I enabled "active solver for 2d constraints".

I have another question, how to draw construction line like in solidworks?
