    FreeCAD

    FreeCAD

    a parametric 3D CAD modeler

    This is an official mirror of FreeCAD. Code and release files are primarily hosted on https://github.com/FreeCAD/FreeCAD and mirrored here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, 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 100% Open Source and extremely modular, allowing for very advanced extension and customization. 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.

    Techne (R) CAD/CAM

    2.5D CAD CAM emphasis on CAM and toolpaths

    A Windows only 2.5D CAD CAM application. The user experience tightly integrates the CAM aspects when doing design and layout. The target users will layout their design and then immediately generate CNC code. The goal is a design application closer to Adobe Illustrator than to AutoCAD. The user specifies machining aspects during object creation so that when the design/layout phase is completed the toolpath generation can occur automatically. What is 2.5D? Objects created are flat (2D) but have a depth component. So you can create a square that will be machined at a specific depth but the depth will be constant accross the square. It is not/does not: A general purpose CAD (AutoCAD) type program. Support reference dimension on the drawing. Export or import major CAD file formats.
