3DTin is a 3D Modeler that runs in your browser.
You can ..
* design models by placing cubes of different colors on top of each other.
* creat shapes from standard templates (WebGL required)
* save the sketches in cloud
* export the sketches in standard 3D file formats - STL, OBJ, Collada
For best user experience, make sure you have WebGL enabled in your browser. For WebGL to work you need a decent graphics card. (If you are still having a problem check this link http://bit.ly/epLszC)
