So the question is, is it possible to change a constraint dimension to reference.

For example, in this screenshot, all three dimension are constraints. I can not change any dimensions because the sketch is over-constrained. Now if I could make the 50mm dimension a reference, then I could change the other two dimensions without a problem.

Your thoughts?

It normally does it itself. If you go to overconstrained situation it'll flash up with a warning, and then make a black bracket dimension.
What I do in this situation is click a line. Go to concept explorer and expand until you find the sketch number , expand that. You'll find sketch axis. Right click it and show it.
I'd then do a coincidence constraint from the line end (bottom left of the view) to the sketch axis origin. That'll kind of fix that bottom corner and then if you drag the axis about the sketch will move.
Then you can push it to an overconstrained situation. All lines turn green when it's fully constrained

>>I can not change any dimensions because the sketch is over-constrained.

As UGMENTALCASE mentions, if your system was fully constrained, it will ask you to apply a reference dimension.

Alternatively, if you use a dimension tool outside the constraint palette, it will not be treated as part of the system of equations to solve.

I made a quick video showing both methods....

Thanks UGMentalCase... I guess I didn't fix the origin. Oops!

@Tim, nice video, Thanks. I did try the standard smart dimension and that worked! Is there a way to convert a constraint dimension into a standard dimension?
