Jesus,
I have a basic Training video o my web-site,
http://www.cad2cam.net/xlathebook.htm either download or CD,They are both the same but download is cheaper I cover: Importing DWG Geometry into Mastercam X , Editing the file for Job set-up, Roughing Both Sides, Finishing both Sides, Rough and Finish Bore and Stock Flip, Also included are Back plot and Verify videos. The DWG File is included that we use to teach this class.
