Faces

Faces are the bounded surfaces that make up the skin of a solid in OCCT. Most modelling paths run through them: draw a closed wire, turn it into a face, then extrude or thicken that face into a solid. These pages cover the face primitives, building faces from a list of points or from a closed wire, and the subdivision helpers that place points or shapes evenly across a face for patterning. A worked example builds a hexagonal grid pattern on a face, which is the basis for most perforated and lattice geometry.
