A method includes receiving () a model () of a part to be manufactured, wherein the model includes a plurality of original faces (). The method includes classifying () each face in model according to a relative face curvature according to classifications that include at least a high-curvature classification (). The method includes classifying () any sliver faces () and narrow blend faces () of the plurality of faces. The method includes merging () contiguous faces () in each classification. The method includes detecting () special faces () of the plurality of faces. The method includes restoring () original faces in the high-curvature classification except for the special faces ().
