I am trying to detail out a fixture mounting plate that has keyways that are for alignment of linear rails and I have (6) 1/2-13 holes that go through the fixture plate but (2) of then break into the edge of the keyway so instead of having a complete circle for the hole I have (2) arcs. When I try to select the arcs to add to the hole table SolidWorks will not add the holes to the table. See the attached images that show the part and the drawing. I don't want to use the opposite side of the plate to call out the hole locations because then all of the holes would be on the opposite side that they will be machined on.

Is this another bug in SW 2015 or is there a way to add the holes that break into the keyway?

Thanks

Tony
