Subject: Re: [Homebrew_PCBs] CadSoft Eagle pads question

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.
