I have been trying to figure out how to engrave these drawings that i downloaded from here with no success. See attached files. I have tried all these programs and cannot seem to create a tool path to engrave lettering. SOLIDWORKS 2015 x64 Edition, ArtCAMPro, Autodesk Inventor Professional 2016. I can create a tool path to cut holes and the outline of the drawing but no lettering. Can anyone steer me on the right path? Maybe a good diagram of what you have done would be helpful to try to follow it. Thank you very much for any help you can assist me with.
