What is the difference between PCB Creator and Diptrace?

PCB Creator is a feature light version of Diptrace so the look and operation of the software is very similar. Because BAC distributes PCB Creator free of charge, some of the feature limitations include a limit on layer count (up to 4) and a limit on the number of pins allowed. Additionally, PCB Creator only allows for the export of files in a .BAC format, proprietary to Bay Area Circuits. PCB Creator users who purchase their PCB design from BAC will be provided with Gerber files upon request.
