In elementary geometry, a face is a polygon on the boundary of a polyhedron. Other names for a polygonal face include polyhedron side and Euclidean plane tile. For example, any of the six squares that bound a cube is a face of the cube. Sometimes "face" is also used to refer to the 2-dimensional features of a 4-polytope. With this meaning, the 4-dimensional tesseract has 24 square faces, each sharing two of 8 cubic cells. WebApr 13, 2024 · Face Count. The number of faces that use the edge as one of their sides. When the value is one, the edge is a non-manifold boundary edge. Alternatively, when the value is zero, the edge is a loose edge, not used by any faces. Examples Using the Face Count output to create a curve on a mesh’s boundary edges.
