FreeCAD
FreeCAD will be a general purpose 3D CAD modeler. The development will be completely Open Source. As with many modern 3D CAD modelers it will have a 2D component in order to extract design detail from the 3D model to create 2D production drawings, although 2D (e.g. AutoCAD LT) is not the focus, neither are animation and organic shapes (e.g. Maya, 3D StudioMAX and Cinema 4D).
FreeCAD is aimed directly at mechanical engineering, product design and related features like CatiaV4 and V5, SolidWorks and Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE. It will be a feature based parametric modeler with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.

VIZup
VizUp 1.8 (last freeware version)
Many of the models that you create with the help of 3D modeling tools, as well as some models converted from CAD software can be very complex. These models may consist of hundreds of thousands, even millions of polygons and are practically useless for processing in real-time visualization systems. VIZup is an easy-to-use tool for reducing and optimizing 3D models. With the help of VIZup, you can reach the optimal balance between the necessary details level and the size of 3D models. You can also use this software to reduce the number of polygons for your 3D models used in virtual reality and real-time visualization systems. Decreasing the size of 3D models stored on the Web lets your users and customers download them much faster. Besides, this product can also be effectively used for Level-of-Details (LOD) generation.
