- Angular Deflection: Determines the angle between adjacent facet normals along curved fillets, ensuring smooth circular silhouettes without polygon stepping.
- Manifold & Watertight Validation: Verifies that meshes have no open edges or non-manifold junctions before export into slicing software like Cura or PrusaSlicer.
