Think I have a gremlin in my system, strange things keep happening.
Last few day when I do an Extruded cut about half the time on the 1st try it refuses to do the cut. But acts like it did with no errors. To get the cut to work I have to close then reopen the part. Delete the cut Extrude, put it right back in again same plane same dimensions everything. This time it works.
Before I put it back in I tried a rebuild and Ctrl Q. I saved and closed the part. Cut still was not there when I reopened it. Deleted cut and Sketch for it. And as I said when I put it back in worked fine.
Any body else .
