libfive is a C++ framework and geometry kernel for solid modeling using functional representations (f-reps), with a C API, Scheme and Python bindings, and a standard library of shapes and CSG operations. It also includes Studio, an OpenSCAD-style desktop GUI for live-coded, parametric solid modeling with direct manipulation.

Use cases

• build a custom CAD application on a solid modeling kernel
• create parametric 3D models from scripts for 3D printing
• generate watertight manifold meshes from implicit surfaces
• run headless CAD model generation as a design customizer service
• do constructive solid geometry with blends and warps
• live-code solid models in Scheme or Python

When to choose

• you need programmatic or procedural solid modeling rather than manual mesh editing
• you want robust CSG, blends, and warps on implicit surfaces
• you're building domain-specific CAD tools and need a commercially friendly (MPL) kernel
• you want high-resolution meshes from f-rep geometry

When to avoid

• you need a traditional polygon-mesh or NURBS-based CAD workflow
• you want a polished end-user CAD app rather than a library/framework
• you need extensive official documentation or commercial support out of the box
• your project requires a permissive license for the GUI component (Studio is GPL)
