Most of OCCT functionality is available in the form of C++ libraries. OCCT is ideal for developing software dealing with 3D modeling (CAD), manufacturing\u002Fmeasuring (CAM), or numerical simulation (CAE).\n\n## License\n\nOpen CASCADE Technology is free software; you can redistribute it and\u002For modify it under the terms of the GNU Lesser General Public License version 2.1 as published by the Free Software Foundation, with a special exception defined in the file `OCCT_LGPL_EXCEPTION.txt`. Consult the file `LICENSE_LGPL_21.txt` included in the OCCT distribution for the complete text of the license.\n\nAlternatively, Open CASCADE Technology may be used under the terms of the Open CASCADE commercial license or a contractual agreement.\n\n**Note:** Open CASCADE Technology is provided on an \"AS IS\" basis, WITHOUT WARRANTY OF ANY KIND. The entire risk related to any use of the OCCT code and materials is on you. See the license text for a formal disclaimer.\n\n## Packaging\n\nYou can receive certified versions of OCCT code in different packages:\n\n- **Snapshot of Git repository:** Contains C++ header and source files of OCCT, documentation sources, build scripts, and CMake project files.\n- **Complete source archive:** Contains all sources of OCCT, generated HTML and PDF documentation, and ready-to-use projects for building on all officially supported platforms.\n- **Binary package (platform-specific):** In addition to the complete source archive, it includes binaries of OCCT and third-party libraries built on one platform. This package allows using OCCT immediately after installation.\n\nCertified versions of OCCT can be downloaded from:\n- [Open CASCADE Releases](https:\u002F\u002Fdev.opencascade.org\u002Frelease)\n- [GitHub Releases](https:\u002F\u002Fgithub.com\u002FOpen-Cascade-SAS\u002FOCCT\u002Freleases)\n\nYou can also find OCCT pre-installed on your system or install it from packages provided by a third party. Note that packaging and functionality of such versions can be different from certified releases. Please consult the documentation accompanying your version for details.\n\n## Documentation\n\nDocumentation is available at the following links:\n- [Latest version](https:\u002F\u002Fdev.opencascade.org\u002Fdoc\u002Foverview)\n- [Version 7.8](https:\u002F\u002Fdev.opencascade.org\u002Fdoc\u002Focct-7.8.0\u002Foverview)\n\nDocumentation can be part of the package. To preview documentation as part of the package, open the file `doc\u002Fhtml\u002Findex.html` to browse HTML documentation.\n\nIf HTML documentation is not available in your package, you can:\n\n- **Generate it from sources:** You need to have Tcl and Doxygen 1.8.4 (or above) installed on your system and accessible in your environment (check the environment variable PATH). Use the batch file `adm\u002Fgendoc.bat` on Windows or the Bash script `adm\u002Fgendoc` on Linux or OS X to (re)generate documentation.\n- **Generate together with sources:** You need to have CMake and 1.8.4 (or above) installed on your system. Enable `BUILD_DOC_Overview` CMake parameter and set the path to Doxygen `3RDPARTY_DOXYGEN_EXECUTABLE`. Then build ALL or only `Overview`.\n- **Read documentation in source plain text (Markdown) format** found in the subfolder `dox` or [GitHub Wiki](https:\u002F\u002Fgithub.com\u002FOpen-Cascade-SAS\u002FOCCT\u002Fwiki).\n\nSee [dox\u002Fbuild\u002Fbuild_documentation\u002Fbuilding_documentation.md](dox\u002Fbuild\u002Fbuild_documentation\u002Fbuilding_documentation.md) or [Building Documentation](https:\u002F\u002Fdev.opencascade.org\u002Fdoc\u002Focct-7.8.0\u002Foverview\u002Fhtml\u002Fbuild_upgrade__building_documentation.html) for details.\n\n## Building\n\nIn most cases, you need to rebuild OCCT on your platform (OS, compiler) before using it in your project to ensure binary compatibility.\n\nConsult the file [dox\u002Fbuild\u002Fbuild_occt\u002Fbuilding_occt.md](dox\u002Fbuild\u002Fbuild_occt\u002Fbuilding_occt.md) or [Building OCCT](https:\u002F\u002Fdev.opencascade.org\u002Fdoc\u002Foverview\u002Fhtml\u002Fbuild_upgrade__building_occt.html) or [Building OCCT Wiki](https:\u002F\u002Fgithub.com\u002FOpen-Cascade-SAS\u002FOCCT\u002Fwiki\u002Fbuild_upgrade) for instructions on building OCCT from sources on supported platforms.\n\n## Version\n\nThe current version of OCCT can be found in the file [`adm\u002Fcmake\u002Fversion.cmake`](adm\u002Fcmake\u002Fversion.cmake).\n\n## Development\n\n### Bug Tracker\n- [GitHub Issues](https:\u002F\u002Fgithub.com\u002FOpen-Cascade-SAS\u002FOCCT\u002Fissues)\n- [OCCT Tracker](https:\u002F\u002Ftracker.dev.opencascade.org\u002F)\n\nFor information regarding OCCT code development, please consult the official OCCT Collaborative Development Portal:\n- [OCCT Development Portal](http:\u002F\u002Fdev.opencascade.org)\n\n### Forum and Discussions\n- [OCCT Forums](https:\u002F\u002Fdev.opencascade.org\u002Fforums)\n- [GitHub Discussions](https:\u002F\u002Fgithub.com\u002FOpen-Cascade-SAS\u002FOCCT\u002Fdiscussions)","Open CASCADE Technology (OCCT) 是一个开源的软件开发平台，专注于3D CAD、CAM和CAE应用。它提供了丰富的C++库，支持3D表面与实体建模、CAD数据交换及可视化等功能。OCCT适合于需要进行三维建模、制造\u002F测量或数值模拟等工作的软件开发场景。无论是从零开始构建复杂的工程设计工具还是增强现有应用程序的功能，OCCT都能提供强大的技术支持。此外，该项目还提供了多种分发包形式，包括源码存档、二进制包以及预编译好的第三方库，方便用户根据自身需求选择合适的版本进行开发或直接使用。",2,"2026-06-11 03:32:21","trending"]
