Hi, does anyone out there know of where I can get my hands on files of a car seat that I could use as the starting point of my design? I'm using Autocad Inventor 2010 and, as I'm extremely new to it ( not bad at LT2011 ) any help on obtaining a car seat would be greatly appreciated. Failing that looks like I might have to measure my everyday car seat and use that as a guide!!

Don't know of any files, but here is a PDF layout,

and Chris Gibbs book has a layout too.

Have you looked at 3dcentral?

Already a member on 3Dcentral, thanks. The prob with that site seems to be the drawings aren't compatible with Inventor 10 for some reason.
The aluminium seat details are interesting, thanks.
