Here is a simple SM part that I want to add a cut out in the unfolded condition. When the part is folded I want the top of the cutout to be 10mm from the base. I'm not sure how to dimension the part so that when it's folded I get the 10mm dimension. As you can see the current dimension shows 9.47. I would like to do this without trial and error (get it done the first time)
