CO2 Shell Dragster Tutorials
Welcome to cudacountry's SOLIDWORKS 2016 and Mastercam 2017 CO2 Shell Dragster Tutorials. At cudacountry we use SOLIDWORKS 2016 to design our cars and Mastercam 2017 to create CNC toolpaths to cut the car body. The following tutorials with the PDF icon are available for viewing.

The 2016 CO2 Shell Car Tutorials include Mate References on parts concentric with Axles.
Here are 2015 tutorials. It's highly recommended to use the new 2016 tutorials.
