I am relatively inexperienced with SolidWorks and am having difficulties with an imported model.
Currently, I am being given the following error when I attempt to cut with a sketch.
I have drawn a sketch with 4 slots, so I don't believe there is an open contour. I have tried flipping direction, side to cut, and using through all - both without success.
Is there an obvious reason for this cut not working that I am missing?
