Dear,

I've been busy building this car in Rhinoceros 4 for a school project (I also built my own wind tunnel) but now I want to put this car in the virtual Solidworks wind tunnel.

• But it keeps on saying that my car has to become a body, but how to do that?
• How to calculate the Drag coefficient with Solidworks? The formula for the Drag coefficient is: http://en.wikipedia.org/wiki/Drag_coefficient

I can also calculate it myself but then I've got to know:

1. the speed (i know you can adjust that, and i know how to)
2. the density of the air (i do also know that)
3. the reference area (i don't know how to do that)
4. the force of the drag (i don't know how to do that either)

This is the car: https://fbcdn-sphotos-d-a.akamaihd.net/hphotos-ak-prn1/857430_10200258026206396_48873402_o.jpg

Thank you very much!
