I copied a small 3D object and stored it as a dxf file. Nothing seems to open it, I get an invalid headers in the file, format not recognized error. I've tried several software packages to see what would happen, same error. I tried FreeMill, Rhino 3D and Parts Wizard for kicks.
For 2D, the dxf file imported easily into parts wizard.
Could some on briefly outline the process for taking a 3D file and working with it? Did I just get a bum file and need to try again? What software are you using?
Thanks,
Robert
