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.


Table of Contents

Part 1. Blank. Units are all metric.

2. Body. Style Spline in sketches for side and bottom cuts.


3. SW16 to Mastercam 2017. In this new 2017 tutorial you open your SW body file in Mastercam 2017. In Mastercam 2017 the solid body is moved to Mastercam origin. Next, create two WCS planes to position solid body into the correct Mastercam XY axis. Then create check solid.
4. Mastercam 2017 HST toolpaths to cut shell car body from balsa blank: 1) Bottom shell wheel cutouts using very cool rough Area Clearance deep plunge Trochoidal elliptical cuts and finish Raster. 2) Cut body left side using finish Hybrid toolpath. 3) Mirror left cut to right side cut.
Part 5. Front Wheel GT-F.
Part 6. Rear Wheel GT-R.
Part 7. Front and Rear Axles.
Part 8. Front and Rear Spacers.
Part 9. Washer.
Assembly 10. Assembly.
Drawing 11. Drawing. 11” by 17” paper.
Part 12. Eye Screw with Threads and Mates.
Part 13. Cartridge with Mates.
14. Decals. Flames and Band decals for Body. Click here for decal files.
15. Render. Add Camera and create rendering using PhotoView 360.
16. Analyze in Wind Tunnel. Analyze assembly design using Flow Simulation and create animation of flow trajectories. Our best was 12.72 drag! Can you design car with less drag?
Part 17. Axle Retainer.
Part 18. E-Clip.
Part 19. Hair Pin Clip.


  20. Mastercam 2017 for SOLIDWORKS Toolpaths. Start with rotating solid body into the correct Mastercam XY toolplanes to cut car from balsa blank. Next, create bottom cut shells toolpath using very cool Area Rough deep plunge Trochoidal elliptical cuts. Create side cuts with left cut finish Hybrid toolpath and mirror to right cut all within SOLIDWORKS.
Here are 2015, 2012, 2011 and 2010 tutorials. 2016 is recommended.

Body cut extrude sketches are now drawn with the Style Spline! Using Style Spline improves ability to thread spline between blank edge and wheel shells and fully define by dimensioning control vertex points. Here's bottom cut Style Spline...
