3D scanning campaign look!!!!
 

I have a campaign up right now to get donations to buy a 3d scanner I am going to scan in bare chassis and compile a database of free downloadable CAD files. People can then go and download the chassis that they have and open it as a solid model to design parts off of. It is a big number but if everyone gives what they can then there will be a database that could cut down fabrication time and guessing how far the trans tunnel hole is what is the location of the subframe studs, etc

That sounds like a cool project!
FYI there is a lot of software which does the same thing, using just an ordinary camera.

All it would take is access to a junkyard and a few days/weeks.

That is true but the accuracy is +/- 2-3 thousands which by the time you get to the end of the car can add up to inches the scanner I'm going to get is accurate up to 40 microns or half the thickness of a human hair.
