Looking for an engine model

Hi guy for a University project i have to use a cummins 4bt3.9g3 i have tried drawing it up from the cad file university have given me but there are a bunch of missing dimensions which is making it awkward to draw even a basic model

I if anyone knows where i have to look that would be a great help

Yours Sincerely Smokes

you might try getting online with the engine manufacturer.I have (in the past) gone to another manufacturer and gotten models of the engine so we could model our machine and make sure the engine would work the way we wanted it to.

http://boatdiesel.com/ this is a really good place to start

Well i have e-mailed cummins asking for a 3d parasolid they said try the uk distributors but so far no reply.I have drawn a basic mock up with the 2d cad drawing give but not too happy with the final result.
