In dimension style settings dialog I see possibilitied to change lines properties for "Invisible edges", "Axes" or "User parts". But what about lines of profiles themselves? How to change them? By now I found a way to do it only using default lineweight of all lines. But in this case lineweight is changed also for elements where it is not necessary...
I change my lineweight in the layers properties. All layers associated with a particular view will begin with "xx____" and the blank spot is your group/assembly name. For example, I have a group named "TopView". The layer's name will begin with"xxTopView_Drawing_....." and there will be several for that group. Try changing these layers' lineweights and see if that helps.
