I have autocad 2000, and am able to draw my woodworking stuff in 2D and my 3D needs. I have mach3 to run the controller and CNC. Do I need anything else? Should I be able to just export the DXF file from Autocad to mach3 and it translates it? Is there anything I'm missing? I'm sure I can do that, but is there a better way? Thanks for any advice!
