CAMMaster is for complex CAM and PCB manufacturing. CAMMaster Designer is a CAD companion tool that simplifies difficult tasks such as layer compare and netlist compare. Netlist extraction and DRC functions reportedly set the industry standard. Can merge data by board layer, reducing the information to a minimal set of polygons. These polygons can be converted to F type outlines to edit, and then back to polygons. Can merge multiple designs and panelize jobs.
