Surface Tangency

Some surface operations such as fillets and corners maintain surface tangency during their construction. Such surface areas should not be reconstructed from their boundaries as recommended here for other surface areas. Even though their boundaries would be the same, the surface patch operation does not take tangency into account and the resulting surface may differ from the one it is intended to replace. This is especially true for the corner surface operation.
