Locate and diagnose problems in geometry imported from other CAD software. Then, use surface tools to repair the damaged geometry. Diagnose problems in a model with verification on rebuild, import diagnostics, and check entity. Heal faulty faces using the import diagnostics tool. Delete faulty faces and use various surface tools to re-create the geometry. Display curvature and check the minimum radius of curvature. Delete and replace fillets to create smoother blends. Extend, trim, and knit surfaces.
