I work for BobCAD CAM the software company and wanted to share some information about our Express software. The following 3 videos go through the work flow of drawing a part, setting up your CAM Tree, creating tool paths, and making copies of your tool paths. No matter what CAD / CAD CAM system you use to create your designs these videos will help you understand some key concepts about CAD CAM . You may create a cnc router, or a plasma cutter, or maybe even a gluing machine, and the work flow would be the same. The only thing that would be different would be your tooling information and maybe how deep your are cutting. I am sharing this information because I think it will help any new CAD CAM users understand some basic concepts and see a project from start to finish.
