    Fatigue may not be critical IF you specify a large enough ultimate load. It also depends a lot on the geometry of the part and how it has to be configured to take the load.

    Probably preferable to 3D scanning is getting someone to measure the points of importance on a CMM. Our laser scan of the CBR600RR is really unusable.

    An amusing thought. I don't even think most working FSAE cars would qualify under those requirements. http://fsae.com/groupee_common/emoticons/icon_smile.gif

    It would probably help if you did up a quick sketch. Bodywork should easily support itself under most FSAE conditions, but we don't know what else you have hanging off of it, or what your operating...

    Using your mould as final bodywork will do one of two things.
    1) Give it a really poor surface finish, or
    2) Result in a very heavy final structure
