FreeCAD will be a general purpose 3D CAD modeler. The development is completely Free Software (GPL & LGPL License). FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties.
FreeCAD features tools similar to Catia, SolidWorks or 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.
The goal of this project is to develop a fully fledged and extensible 3D CAD application based on the concept of
parametric modeling of solids, comparable to well known solutions like SolidWorks or Alibre Design.
The main categories of functionalities that naroCAD will have are:
- Parts modeling (specifications detailed in Chapter 3)
- Assemblies (specifications detailed in Chapter 4)
- Drawings (specifications detailed in Chapter 5).
These functionalities are interrelated through Model Associativity and are exposed through a GUI. The
application can be extended through Plugins and programming interface.

CAELinux is a computer aided engineering Linux distribution.They say you just insert the CAELinux LiveDVD in a computer and turn it into a professionnal CAE workstation.
It is based on the open-source CAE softwares Salomé, Code_Aster, Code_Saturne and OpenFOAM , you can load your CAD geometry in Salomé and start partitionning and meshing your problem in just 5 minutes.
Then you can simulate incredibly complex physics with the open-source FE & CFD solvers Code_Aster, Code-Saturne, OpenFOAM & Elmer: non-linear thermo-mechanics, coupled fluid-structure dynamics, seismic / non-linear explicit dynamics, contacts, visco-plasticity, fluid dynamics, heat exchange, convection heat transfer and radiation, electro-magnetcis in other words nearly all physics problem can be addressed with the integrated solvers!! Then reload your results files in post-processing applications like Salomé, GMSH, Visit, or Paraview to visualize your data in 3D… And don’t forget all these features are based on free softwares.

BRL-CAD is a powerful cross-platform open source solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, image and signal-processing tools, a system performance analysis benchmark suite, libraries for robust geometric representation, with more than 20 years of active development.
QCAD is an application for computer aided drafting in two dimensions (2d). With QCAD you can create technical drawings such as plans for buildings, interiors, mechanical parts or schemas and diagrams. QCAD works on Windows, Mac OS X and many Linux and Unix Systems. The source code of the QCAD community edition is released under the GPL (Open Source).
QCAD was designed with modularity, extensibility and portability in mind. But what people notice most often about QCAD is its intuitive user interface. QCAD is a simple 2D CAD system for everyone. You don’t need any CAD experience to get started with QCAD immediately.
SALOME is a free software that provides a generic platform for Pre and Post-Processing for numerical simulation. It is based on an open and flexible architecture made of reusable components available as free software.
Characteristics:
- Supports interoperability between CAD modeling and computation software (CAD-CAE link)
- Makes easier the integration of new components on heterogeneous systems for numerical computation
- Provides a generic user interface, user-friendly and efficient, which helps to reduce the costs and delays of carrying out the studies
- All functionalities are accessible through the programmatic integrated Python console
Main Functions
- Create/modify, import/export (IGES, STEP), repair/clean CAD models
- Mesh CAD elements, check mesh quality, import/export mesh (MED, UNV, ASCII)
- Handle physical properties and quantities attached to geometrical items
- Perform computation using one or more external solvers (coupling)
- Display computation results (scalar, vectorial)
