How do we open it ? I want it in Photoshop CS3 Extended and it doesn’t work. They can’t read it.

It is a 3D model created in the 3DS 3.0 format. You can download it as either 3DS or 3DXML, both of which are still 3D formats. Here on 3DVIA, you can click on “PLAY 3D”, wait for it to load and then move it around to the position you want and do a screen grab in the format you’re used to. Then you can pull it up as a 2D image in Photoshop.
