Tom Hudson created CAD-3D, Stereo CAD-3D 2.0, and Cyber Sculpt for the Atari ST computers. These applications are used for creating 3D objects.

The first version of CAD-3D saved objects in .3D files. Stereo CAD-3D 2.0 and Cyber Sculpt saved objects in .3D2 files.

This web app lets view the objects in both file types.
