|Sewing faces creates one shell or several shells from a set of faces.|
|For that, Sewing faces merges edges which belong to different faces or one closed face. Sewing faces supports two modes, manifold and non manifold. Sewing in the manifold mode creates only manifold shell. For creation of non manifold shells sewing in the non manifold mode should be used.|
Manifold sewing of faces merges only two nearest edges belonging to different faces or one closed face with each other.
Non manifold sewing of faces merges all edges at a distance less than the specified tolerance.
