We just stumbled across another free CAD program called PCBWeb. It includes a feature to order your PCB from a choice of manufacturers and can also create a Bill of Materials (BOM) usable at Digi-Key’s web site to order parts. That sounds convenient (and our guess is that’s how the software publisher will make money). The one down-side we can see is that PCBWeb does not appear to do auto-routing. Nonetheless, we’ve added it to our list of free CAD software.
