Hi, I have found when in a part sketch if I am placing the same geometry in different places I will usually go ctrl c ctrl v and it will create new dimensions and parameters for them, often I want them to be the same as the original. I propose that in the copy dialogue a tick box be added to derive dimensions or the dimension get replaced with an equal constraint to the original line. The deriving parameters seems like it would be more user friendly so you can easily change a dimension if you want to make it mostly the same but different in one dimension. So in the screen shot with dimension derived ticked the copy for d53 would have d<whatever the new dimension is> = d53 rather than 12mm.

This would also be useful for if clipboard is ticked you could then paste it in a new sketch with the parameters driven.
