Draw3D is a freeware modeller for creating / modifying 3D objects.

File Support:
Compressed Draw3D (.D3D) files (stores everything you would want to store, yet is very small, and can even be zipped even smaller!)
3D Studio (.3DS & .ASC) files (for use with other modellers)
Text Spreadsheet (.CSV) files (can open in MS Excel as a spreadsheet, or edit yourself)
Old Draw3D (.3D) files (for compatibility with Draw3D v3.2)
Also Exports to:
VRML 1.0 (.WRL) files (for interactive web viewing) (NEW)
POV-Ray (.POV) files (for stunning ray-tracing) (NEW)
Windows Bitmap (.BMP) files (for simple output) (NEW)
AutoCAD (.DXF) files (for transfering to other CAD packages) (NEW)
Object Creation:
Can create Polygons, parametric NURBS Curves & Circles (NEW), Grids, Cubes, Cylinders, Spheres, Sweeps (Revolutions) and Extrusions.
Parametric Curves:
Can interactively change all curve parameters even after Draw3D has been closed. NURBS weights can be changed easily. Can add extra control points by holding down the ’Control’ key & left clicking.
Lists:
Has lists of most items, so that you can view & modify them easily.
Interaction: You can use the Numpad keys (on the right side of your keyboard) to move / rotate / zoom the 3D View, as well as the most recently clicked view. (NEW)
Skins: Can save different skins / configurations
Undo system: Can undo every operation (even overwriting files!), with unlimited undos for most operations.
Color: Greyscale, 256 Colors, 8-bit, 16-bit, 24-bit or 32-bit color, on any display.
3D Shading: Renders in full-colored & sorted Wire-frame, Flat-shaded or Gouraud Shaded triangles, with optional Z-Buffering rather than sorting.
