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. -

The 1-dimensional gas-dynamics code. More information in http://www.openwam.com Modeling is an important technique for the optimization of internal combustion engines (ICE). The use of calculation models together with experimental tests is producing unquestionable successes due to the fact that both techniques complement each other. 1D wave action models simplify the engine by means of ducts, where only one dimension is considered, and volumes where mass accumulation is considered and the gas properties are uniform in the entire element. Finally, non dimensional models are used to solve connections between 1D and 0D elements. Thanks to more than 20 years, more than 10 PhD Thesis and many research projects and publications, CMT-Motores Térmicos has developed an own 1D gasdynamic tool called OpenWAMTM which gathers an important know-how on air management, compressible flow, turbocharging, chemical species tracking, numerical analysis and many other aspects of engine modeling.

Lima VVA
Simple Road Design and Earthworks
Lima VVA is a lightweight Windows application for road design and earthwork calculation. It is suitable for small to medium projects, where ease-of-use, low cost and quick results are paramount. It lets the user design the road interactively, while the geometry and earthwork quantities are automatically calculated in the background. By manipulating the construction parameters, other earthworks can be calculated, such as ditches, embankments, land fills, building sites — in short, anything suitable for the cross-section method. The program produces high quality drawings, reports, and construction data for the design. These results can be exported to other systems such as office, CAD and GIS software, surveying equipment, and systems for automated machine control. -
