Homebrew PCBs

Alan,

The usual workflow is to first workup the schematic, and later drag the 
parts into place on the board. You should find more part libraries on the 
Cadsoft site than you can use. In general, the parts associate one or more 
packaging options, each defining the appropriate copper, drill, soldermask, 
and silkscreen. The limitation on the freeware is board size and complexity, 
not the parts libraries.

Mike.
