Step-by-Step Tutorial: Homework of Session 4

Hello everybody!

I haven’t got any CAD software installed in my PC but SketchUp at the moment. I’m working with the reference front wing you gave us. I have noticed that with OnShape I can export the parts in the file to .stl files, but not the surfaces (which I’m interested in). Can anybody help me please with this?.

Thank you!
