Autodesk 123D free 3D software

[www.123dapp.com]

It is a suite of free 3D programs.
123D - 3D model program
123D Catch - turns photographs into 3d models
123D Make - turns 3D models into flat patterns to be cut from.

I am going to download the applications here today and compare them to the other Autodesk programs (Inventor, Mudbox, 3DS Max)

Anyone read or heard about this?

I have been using 123D for four months. Works great for the design of printed parts. STL files work great.
There is a design tools section in this forum. Let us know what you think.

if you're used to inventor or solidworks you wil find it to be very gimped. very few features
