The three-face blending operation creates a blend surface from one set of smoothly connected faces to another such set. The blend surface will be constructed tangent to yet another, third set. A typical situation addressed by this operation is creation of a smooth transitional surface between two opposite faces and along the narrow strip of the side surface of thin-wall parts. The sets of faces for blending are not required to share common edges (intersect).
