to offer a free and easy to use software
I started making my models with 223D-Design. So I learn to know 3D-Hubs. 123D-design isn't exsisting anymore.
It would be perfect when you offer a free and easy to use stand alone software for creating 3D models, that works in the same way as 123D-design.

123D Design wasn't made or released by 3D hubs, they are a printing service not a software manufacturer...
