Circuitworks

Hi Solidworkers,
I'm having a bit of a problem. When I import a pc board.idf file from Mentor Graphics and import it to solidworks,it comes in fine, but when I make my changes to the part I try toimport it back into Circuitworks, and the changes don't show up.All I'm doing is adding a Hatch sketch and 4 little holes. What amI doing wrong?

ThanksSolidworksCircuitworks
