Rhino

Rhino is a powerful surface modeling tool that we are going to use to create the aerobody. 

Overall Steps:

  1. Add background bitmap to the orthographic views in Rhino 
  2. Draw 2D curves that represent key inflection points on the surface of the car
  3. Use the "curve from two views" tool to project the curve into 3D. Then rebuild the curve to simplify it 
  4. Create surfaces from the curves. Use sweep between 2 rails as much as possible
  5. Blend surfaces with fillets, blends and other features
  6. Create closed polysurface (solid body)
  7. Rotate the model so that the wold frame aligns with the global coordinate system for MSXII.
  8. Downgrade the file to Rhino V4 for Solidworks 2015 compatibility or export it as an IGES
  9. Import the solid body into Solidworks and use the shell tool to make it a think aerobody panel
  10. Add an holes and mounting features to the panel in Solidworks

Tips

  • Simple is better - Try to start with simple surfaces (sweeps are good)
  • Blend the fillets between surfaces after the fact. Don't to make surfaces that are curvature continuous right off the bat
