I’ve been working on a web platform called iteration3d, which allows users to generate custom 3D models based on their own dimensions using parametric templates. The entire model generation process is powered by build123d, a Python CAD library built on top of OpenCascade. Every 3D preview and thumbnail is automatically rendered using Blender through a fully automated server-side pipeline. Beyond simply offering a free on-demand service, iteration3d also serves as a practical showcase of what’s possible with build123d. This growing CAD library is quickly gaining attention in the Python and parametric modeling communities. If you're curious about how everything works, I’ve written a detailed tutorial explaining the model-generation process using build123d (see link) The project has also been referenced by OpenCascade, the geometric kernel behind build123d and widely used in software like FreeCAD.
