I have used a 0.375x8 flat bar weldment and (2) 2x2x0.25 L angles to form a side frame and added some cut outs and holes.

When I change the 0.375x8 flat bar profile to a 0.5x8 bar profile it seems to rotate. How can I prevent this so I don't need to remake all of my features?

Both of the weldment profile sketches are the same, only 0.125 difference in width.
