Hi.
Recently has been released a new version of Blender 3D.
The Main new features of this version are the Freestyle Renderer for cartoon style renders and the 3D Printing addon, to help with 3D printing as well as a new ruler tool and mesh-analysis display attributes such as thickness, sharp-areas and distortion.
