Description:

Open CASCADE Technology (OCCT) is the only open source full-scale 3D geometry library. Striving to be one of the best free cad software kernels, OCCT is widely used for the development of specialized programs dealing with the following engineering and mechanical domains: 3D modeling (CAD), manufacturing (CAM), numerical simulation (CAE), measurement equipment (CMM) and quality control (CAQ). Since its publication in 1999 as an open source CAD software kernel, OCCT has been successfully used in numerous projects ranging from building and construction to aerospace and automotive. ArchitectureOpen CASCADE Technology consists of C++ classes grouped into Packages. They are organized into Toolkits (libraries), and the latest are grouped into seven Modules. You can download Open CASCADE library totally free and use it at any PC with Windows, macOS or Linux. Please refer to our Download page for easy OCCT access. If you are interested in OCCT open-source code, go to the Git Repository for simple git access without registration.Foundation ClassesModeling dataModeling AlgorithmsData ExchangeVisualizationApplication Framework (OCAF)Draw Test Harness OCCT comes with algorithms for:Construction of primitives (box, sphere, cylinder, cone, torus, wedge)Computation and comparison of distances between shapesConstruction of prisms and pipesSurface extrusion/revolutionDefining offset surfaces/curvesDefining fillets and chamfersBoolean operations (input, common, cut, fuse.) Data Exchange module allows developing OCCT-based applications that interact with other CAD systems by writing and reading 3D models to and from external data in open and vendor-neutral formats.This tool handles various problems of interoperability between CAD systems, caused by differences in model validity criteria and requirements to internal representation.Supported formats:B-Rep: STEP (ISO 10303), IGES, BREP (native)Mesh: glTF, VRML (ISO 14772), OBJ Wavefront, STL OCCT visualization toolset provides:Cross-platform renderer based on OpenGL and OpenGL ESCompatibility with mobile, embedded (OpenGL ES) and web (WebGL) platformsBuilt-in photo-realistic Ray-Tracing engine supporting global illuminationClipping planes/box with cappingPBR metallic-roughness material workflowFast algorithms picking objects by mouse Should you have more particular queries (for example, how to read dwg files in OCCT or what is the easiest free cad drawing software to use for your specific purposes etc.), one of the ways you can get support is reading blog or posting on OCCT forum, where all the questions are very welcome. Use casesOpen CASCADE Technology is also a backbone of many good projects. For example, FreeCAD providing parametric 3D modelling, drafting and many other capabilities is easy to use for beginners. KiCad – free 3D CAD software for PCB layouts design. Gmsh – a fast meshing tool. Salome – a platform for numerical simulation. CAD Assistant – a powerful viewer and converter.
