I can clear the contour of this piece with two 2D Adaptive operations, one on the left side contour and one on the right one.
But if I try to select both of these same chains in one 2D Adaptive operation, Fusion freezes and has to be killed.
I've seen this before when in some cases 2D Adaptive would refuse to generate a toolpath when such symmetrical selection was done. Freezing/crashing is new and annoying.

P.S. Selecting the entire contour seems to be OK too, but I don't like to select parts of the piece that I know are inside the vise.
