Thanks folks, I am trying to rebuild my parts and texture collections. These two sites are brilliant. Something I have found useful is fbx files, a way to get 3ds.max files into Sketchup via Blender OR the universal import plugin found here on Sketchucation. https://sketchucation.com/forums/viewtopic.php?f=323&t=71951&hilit=universal+importer or in the store.
