CO2 Rail Car Dragster

Welcome to cudacountry's SOLIDWORKS 2016 and Mastercam X9 CO2 Rail Car Tutorials. We use SOLIDWORKS 2016 to design our cars and Mastercam X9 to create CNC toolpaths to cut the car body.

New in 2016:
Style splines take over all splines.
Thread wizard for eye screw threads.
Body uses two configurations for display of two color/decal schemes.

The following tutorials with the PDF icon are available for download. Download the free reader from Adobe.
