I have a glass door that was importedt into SW from a surfacing program. After thickening the part I placed holes in it for mounting hardware and would now like to pass that information on to the glass vendor but I have a problem. When I create the drawing I am unable to select any features to place dimensions. I could probably place points and fudge dimensions, but then it wouldn't be parametric if things change.

Is there a way to convert the part to something that SW can dimension? The glass is curved top to bottom so it isn't just a flat piece.

Thank you

Jim
