Solidworks dimensions?

If it's an incomplete version, I'd say the function has been disabled. It's not that great, anyway, as the automatically generated dims almost certainly won't just happen to coincide with your design intent. Have you used the auto-define sketch function? It's a bit like that - SW does it how it wants, I suppose with as few relations and dimensions as possible, which may or may not work well for one design or another. I find that it takes just as much time to go through and see what it's done and then determine how well it works for that particular situation as it does to simply go through and define the sketch/dim the drawing on your own.
