CadQuery is a programmatic 3D modeling library and parametric CAD framework that allows for the generation of complex geometric solids and assemblies using a fluent Python API. It functions as a B-Rep geometry engine, enabling the construction of models through code rather than a graphical user interface. The project is built on the Open CASCADE Technology kernel and utilizes a method-chaining API to link geometric commands in sequence. It distinguishes itself through a workplane-based coordinate system and a powerful selection system that uses topological and spatial filtering to target spec
Chili3D is a browser-based parametric 3D modeling tool that uses boundary representation (B-Rep) to define and manipulate precise solid geometry. It functions as a constructive solid geometry (CSG) engine, combining primitive shapes through union, difference, and intersection operations, while also serving as a parametric constraint system that maintains geometric relationships and dimensions through adjustable parameters. The software distinguishes itself by running entirely in a web browser without requiring installation, while providing industry-standard CAD file format support for importi
FreeCAD is an open-source engineering design suite designed for parametric 3D modeling, architectural planning, and mechanical assembly. It functions as a professional-grade platform that utilizes history-based operations to allow for non-destructive design updates, enabling users to construct complex geometry through a sequence of constrained sketches and solid operations. The platform distinguishes itself through a highly modular, workbench-based architecture that allows users to tailor the interface and toolsets to specific engineering domains. It features deep Python integration, which se
Fornjot is a CAD modeling kernel and 3D geometry engine designed for the creation and manipulation of precise mechanical shapes. It functions as a B-Rep 3D modeling kernel, using boundary representation to define the shapes and topologies of three-dimensional models. The project provides a B-Rep geometry visualizer to render 3D models in a windowed environment for visual verification. It also includes a pipeline to export internal geometric representations into external data formats for compatibility with other software. The engine covers geometric modeling through primitive-based constructi
SolveSpace is a parametric CAD software and 3D solid modeler. It functions as a constraint-based geometry solver that allows for the creation of 2D and 3D models where positions and sizes are driven by geometric rules and mathematical relationships.
