There are a lot of persons who have heard of “AutoCAD” and know a little bit about what it is used for.  But many are not willing to dish out the $4,000 to get to “play” with it.  Yes, I know you can download a trial version but really how much can you learn about such a powerful program in a trial version?

Additionally, you have some who use it in their work but cannot afford to have a copy on their home PC in order to learn many of its advanced features.  The more you invest in learning about it the more valuable you become to your employer.

Below is a description of a totally free and legal program called “FreeCAD” that is available for download from Sourceforge.net the premier place for Open Source software.

 

FreeCAD is a general purpose Open Source 3D CAD/MCAD/CAx/CAE/PLM modeler, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is a feature-based parametric modeler with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.

FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

The link below will take you directly to the page to download and install this software.  Please be aware it takes a pretty advanced system to run it and run it well.
