The challenge was simple, use the inbuilt DBPro primitive commands to build the 'best' 3D 'modeling' program.

By 'modeling' you should be able to add, delete, and move basic primitive objects. It should at least be functional enough to be able to build a castle (square walls, space in the wall for a gate, cone turrets on the corners). Extra bonus kudos if you can do all manipulation of the primitives with just the mouse (including moving objects up and down ) A selection of media-less textures would be helpful, but not required, saving would again be nice, but not required, Scaling and rotating would be highly recommended but not required, a visual flat grid and or visual indicators as to how your manipulating your primitive would be recommend but not required. An interactive menu would also be nice but not at all required.
