Libraries for 3D modeling, CAD data exchange, and visualization.

Open CASCADE Technology supplies C++ libraries for building applications that create, manipulate and display 3D surfaces and solids. Its CAD data-exchange components support moving models between engineering workflows. Developers integrate the libraries into CAD, manufacturing, measurement or simulation software, using source builds or platform-specific binary packages.

Run modes
  • Library / SDK

    Most OCCT function is C++ libraries for modeling, data exchange, and visualization.

    OCCT README

Install methods
  • Downloadable binary / archive

    Certified platform-specific binary packages include OCCT and third-party binaries.

    OCCT README

  • Build from source

    Git snapshot or the complete source archive, then the CMake build.

Documented platforms
  • Windows / Linux / macOS / Android / Web

    Build document: Visual Studio 2019+ or MinGW-w64 on Windows, GCC or Clang on Linux, Apple Clang or Xcode on macOS, Android NDK, and Emscripten for Web.

    Building OCCT

Resource and setup notes
  • Minimum: CMake 3.10 or later, and a C++17 compiler.

    CMake 3.16 or newer is recommended, and required when BUILD_USE_PCH is on.

    Building OCCT

  • Constraint: A typical minimum adds FreeType for visualization and Tcl/Tk for DRAW.

    The build document says the full third-party set depends on which modules are enabled.
