Create face fillets to modify and repair imported geometry. Define the size and shape of the fillet using selected faces and edges instead of a constant radius value. Use options such as Curvature continuous, Constant width, Tangent propagation, and Hold lines to define the face fillet. Modify imported geometry using a face fillet. Ensure curvature continuity with faces adjacent to the fillet. Set a constant chord length of a fillet. Define a stopping edge, or hold line, for a face fillet.
