i got the dxf or dwg files of the top plate if you want, but it's 2D, and you can import it in sketchup. But it won't be hard to thick it to transform it in 3D.
Yeah I've done top plates and stuff in autocad, I thought it would be handy to have the raw kit dimensions in sketchup.. I might get round to doing that myself and share it in the sketchup 3d library thing.
