I have very simple task and I am unable to do it.
I modeled rectangular slab and I want to delete its corners. I tried drawing two polyline contours and tried to add opening to them but i doesn't seem to work. Then I tried to draw random opening in the middle of slab and then Robot creates openning at the corners also.
I know that I could draw whole slab contour from the beginning but I don't want to do that. I want to be able to make changes to existing slab.
I am attaching my file, if it's not a problem, video would be nice
Corner polylines are in file.
