Need help finding dwg 3D model

[lhg07]

I'm trying to find a dwg 3D model of the Herman Miller Tato, Tatino, Tatone beanbag lounge seating. Does anyone know where I can find this or how to make them? Thanks

Here's some sketch-up models.. if you download the trial version of the full-version of Sketch-up, you can export them to a CAD-friendly format.

The creator claims they're accurate, based on dimensions from the Herman Miller website. The website linked from that page provides a lot of DWG models for their chair designs, but not those specific ones.
