Beam Coping Machine Manual
AutoCAD is and architectural software and works well for exporting flat 2-D pieces to plate processing machines. Where it falls short is in its ability to export files for 3-D shapes like beams, channel, angles etc. AutoCAD exports both DWG files and DXF files which are perfect for plates.
The best part is that many large fabricators have upgraded to a Voortman from a 3-torch. You will be amazed at the results!
