Importing a simple SW board into CW

I'm new to Solid works so be gentle.

I'm trying to make a printed circuit board in Solid works and then import it into circuitworks so I cam pass the mechanical properties to the ECAD engineer.  I just don't seem to be able to import the SolidWorks file into CircuitWorks just to start this process.  I have SW2013 premium which comes with CW.  Can anyone help?

Thanks
