    Open CASCADE Technology, 3D modeling & numerical simulation

    Open CASCADE Technology is a software development kit (SDK) intended for development of applications dealing with 3D CAD data, freely available in open source. It includes a set of C++ class libraries providing services 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.

    The platform is provided by the Company bearing the same name − OPEN CASCADE SAS, which is a subsidiary of EURIWARE. For its clients the Company offers custom development and technical support services. For more information on the Company please visit
