Join the community and share your experience with other members. They carry out various software development projects of different complexity levels in CAD/CAM/CAE domain and discuss them on dedicated forums. Would you like to make your contribution into Open Source software? Open Cascade Community brings together lots of Open Source software developers.

Open CASCADE Technology is available under the GNU Lesser General Public License (LGPL).įull online OCCT documentation, including the Tutorial, User and Developer Guides, as well as other resources, are available on the Open Cascade Collaborative Development Portal. Since its publication in open source, Open CASCADE Technology is a free alternative to expensive proprietary modeling kernels. 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. The typical applications built with the help of OCCT are pre- and post-processors for finite element analysis software, CNC/CMM path generators, numerical simulation programs, etc. Open CASCADE Technology can be best applied in the development of specialized CAD/CAM/CAE applications.

OCCT includes a set of C++ class libraries providing services for 3D surface and solid modeling, visualization, data exchange and rapid application development.

It’s a software development kit (SDK) intended for the development of applications dealing with 3D CAD data. Open CASCADE Technology (OCCT) is a world-known 3D modeling kernel, freely available in open source.
