spex Tabs is an easy 3D software for drawing 3d shapes, printing out the nets of shapes and making 3d paper models. Suitable for pupils aged 6 - 14 years, its an inspired educational software for children which meets a real need in the classroom, and it is great fun for making 3D paper models at home too! aspex Tabs will display the orthographic projection of the model you design, in both the 1st and 3rd angle projection.

Waybe is a plug-in for Google SketchUp that provides a simple toolbar to aid both automatic and manual unfolding of 3D models created within SketchUp. The ability to test unfolds directly within SketchUp allows for faster design cycles, and an interactive print window can fit all unfolded components onto a minimum number of printed pages. Custom page sizes make it possible to scale folded models to any desired size from desktop printers to large plotters.

Bruce Wayne had to sweet-talk Morgan Freeman into girding his Bat-loins with heavy Bat-artillery, but Tony Stark, an engineering virtuoso himself, cajoled not a soul. In a case of life imitating art, the production team behind Stark's iconic body armor Iron Man 2 relied on neither CGI nor gadget-minded elder statesmen, but a bleeding-edge prototyping technology commonly known as 3D printing.

Making papercraft models from 3D data. Works with Craft-ROBO.

The students will use a "real" 3D coordinate system. They will have 3 axes at right angles, and a plane (the XY plane) that will be able to slide up and down the Z axis. The students will then be given several coordinates and asked to find these points in space. They will also be asked to find the coordinates of the 8 corners of a box with given dimensions.
