CAD Kernel

The core software library that implements 3D geometric modeling mathematics — managing solid bodies, surfaces, curves, and operations like boolean union, intersection, and subtraction.

Why it matters

The kernel choice is the most consequential decision in CAD software architecture. It determines data fidelity, geometric accuracy, interoperability capabilities, and the long-term vendor roadmap for any product built on top of it.
