How do you do a PCB layout in Solidworks, board, traces, solder mask and legend??

I need to be able to export this in a standard DXF format for the PCB supplier so he can generate GERBER files to make the boards.

I use to do this in CADKEY with no problem as the different items could be set up a layers.

Please help.....

the is a simple onesided pcb design.
