I'm attempting to extrude cut the profile of Sketch35 (in folder "Top Thicknessing") offset from the face accross from it, with the following parameters (offset is 9/64"). Attempting to apply the cut results in the second image. I would like to know why this might be happening, and how I can work around it; particularly since this wasn't a problem the last time I had this part open. I've attached the part file as well.
Not directly related to the frustration at hand, I'm trying to model a violin.
