Top 6 C++ Opencascade Projects

Opencascade

  1. FreeCAD

    This is the official source code of FreeCAD, a free and opensource multiplatform 3D parametric modeler.

    Project mention: Ask HN: What Are You Working On? (February 2025) | news.ycombinator.com | 2025-02-23

    I'm a long-time FreeCAD user, and one of my annoyances is that long-running operations lock up the entire UI and can't be aborted.

    So for my first contribution to FreeCAD I'm working on fixing this.

    The underlying CAD operations are done by "OpenCascade", and at first I thought OpenCascade had no support for aborting operations part of the way through. So my first implementation was to move the operation into a child process and give the user a dialog box that would allow terminating the child process.

    But it actually turns out OpenCascade does support aborting the operations! So now I'm working on doing it the OpenCascade way.

    My PR is here: https://github.com/FreeCAD/FreeCAD/pull/19796

  4. OCCT

    Open CASCADE Technology (OCCT) is an open-source software development platform for 3D CAD, CAM, CAE.

    Project mention: OpenSCAD: The Programmer's Solid 3D CAD Modeller | news.ycombinator.com | 2024-09-14

    OpenSCAD has been great for simple projects. It’s very easy to get productive with if you know basic programming concepts. However, I’ve run into frustrating limitations on more complex projects. The core geometry engine is skittish.

    I still use OpenSCAD, but I’m diving into the OCCT ecosystem. It has a steeper learning curve, but seems to be significantly more robust.
