How the Unfolding Engine Works
Transform complex 3D geometry into precise 2D assembly nets with our automated computational pipeline.
Input your desired side count or triangulation density. Our engine calculates the manifold mesh in real-time.
“Define your polygon sides and vertex count to begin the calculation.”
