I just got my CNC mill about 2 weeks ago and I am now in the process of learning which CAD/CAM tool I will set myself for life with. At the moment, I am heavily considering SprutCAM for CAM which I will buy if it works out, and AutoCAD 2011 for which I have a license at work.

I just did a very simple part in AutoCAD and as I try to import it on SprutCAM, either nothing comes up or an error pops up. Nothing comes up when I try to import the DWG. Curiously, I can see the part on the preview pane before trying to import. STL files will also come up with nothing.

An error pops up when trying to open the DXF file. No matter what AutoCAD version I save the file under, it states the DXF file can not be opened.

If I do a part in Rhino, it shows up immediately!

Is AutoCAD not a suitable CAD software to work with? Or what am I doing wrong? Thanks!
