I have a line in a sketch that is fully defined but not by a dimension along its length. I need to create an equation for the same sketch that is a function of that length. So I create a dimension along the length and select the “Make This Dimension Driven” option and it is inserted and is greyed out. The problem is that the conflicts that it would have created remain. There is no rhyme or reason when this happens, sometimes it does, and sometimes it doesn’t. Does anyone else run into this?
