When I create a sketch and dimension from a datum plane, the extension line coming from a datum plane doesn't show. Is there a setting to turn on to display this? I can deal with it in sketcher but when I import dimensions on a drawing using Model Items, it gives me the dimension but again without the extension line. I can't drag anything to bring it down if I can't see it.

I believe all you need do is drag the dimension up higher until the extension line appears and then drag the extension line to your part then move the dimension back to its originsl position.
