FreeCAD is a general purpose 3D CAD modeler. The development is completely Open Source (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.
GCAM is the free GNU Computer Aided Manufacturing package. Most 3-Axis Computer Numerically Controlled (CNC) mills such as the Taig, Sherline and Haas are supported in both english and metric units. GCAM has a simple interface for making bolt holes, drill holes, sketches, templates, and more. After extruding these entities one can export the corresponding G-code for the selected cutting tool(s). GCAM also imports RS274X (Gerber) and Excellon drill files for gerber to G-code pcb milling conversion used in circuit board prototyping. Once a design is complete one can export the corresponding G-Code to the appropriate CNC driver of choice such as TurboCNC for DOS or EMC for Linux.
Please use the Discussion Forum to post any questions or suggestions. The GCAM source code is approximately 22k lines of C and is released under the GNU General Public License.
The GCAM source code can also be downloaded from the Files page. Please post all feature requests under Bugzilla.
GLC_Player is a software used to view 3d models (COLLADA 3DXML OBJ 3DS STL OFF COFF Format) and to navigate easily in these models. With the album management, capture and multi-capture capabilities, html export and navigation possibilities GLC_Player is the accurate tools to review a lot of 3D models and to create illustrations.
GLC_Player is a cross-platform application (Mac, Linux and Windows). GLC_Player is a Qt4 application and use GLC_Lib. Source code available.
Open CASCADE Technology – is a software development platform freely available in open source. It includes C++ components for 3D surface and solid modeling, visualization, data exchange and rapid application development. Open CASCADE Technology can be best applied in development of specialized CAD/CAM/CAE applications. The typical applications built with help of OCCT are pre- and post-processors for finite element analysis software, CNC/CMM path generators, numerical simulation programs, etc.
Open CASCADE Technology (former CAS.CADE) exists from the mid 1990-s and has already been used by numerous commercial clients belonging to different domains -− from software edition to heavy industry.
