Quote - the missing part is labled as hydraulic lever

Ah, now it makes more sense.

Quote - i did remove the unneeded parts before i zipped it i thought but forgot to renme the parts

I got two versions of the jackhandle and grip, one pointing forwards and one pointing back, but perhaps that's intended? I don't seem to have a duplicate of the link-arm that markschum mentioned, and the link-arm I have is all one group (as it probably should be).

Quote - and as for making the files poser ready that is one of the big issues i have with not actualy knowing poser... as for the materials they still dont transfer from blender to any software

It's not the Blender materials themselves that are a problem, it's the material zones in the obj files. An obj has one or more material zones that tell Poser what materials are to be applied to what parts of the mesh. In the obj file itself the zones are in 'usemtl' blocks. If you import 10 obj files all with a material zone (usemtl) named "(null)", each obj can use a different material (eg colour, texture map, etc). A figure is different, if 10 of its parts each use a material zone named "(null)", than all those parts will have exactly the same material, eg be the same colour, etc. In your engine lift, both the wheels and the metal bits use a material named "(null)", which would mean they would both have the same colour, etc.
