The end goal is to make all the software available online for any operating system. Why all of the different software platforms? As I understand it, that's just a quirk resulting from different teams working on all the different pieces of software at the same time. It lets you design an object from scratch. 123D is a more traditional design program, rather like AutoCAD, only much simpler and easier to use. Most confusingly of all, there is also a piece of software just called 123D, which is a 3D modeling program currently only available for the PC. It lets you sculpt an object out of virtual clay via a very intuitive and user-friendly interface.

123D Sculpt is a tactile sculpting app for the iPad.

It is currently only available for the Mac.

123D Make lets you slice up 3D models into different 2D pieces that you can then cut out and assemble, as shown in this tutorial.

It is currently only available for the PC. You take a whole load of snapshots of a single object, building or person and the software magically makes a 3D model from them.

123D Catch allows you to convert photos into 3D models.

There's sometimes a bit of (understandable) confusion about what piece of 123D software does what, so here's the run-down:ġ23D is the name given to a small family of different Autodesk programs, all of which are aimed at getting complete beginners involved in 3D modeling. FamilyGuy2006 is right: the PC software and the Mac software are very different.
