The section comes from a set (a 2D mesh or element faces), the mesh already on the source faces (tagged, or a neighbouring body's boundary lying on them, whose nodes are shared so the meshes conform), or a fresh quad mesh of one planar face. Target and side faces project through the tet mesher's B-rep projection. Replaces the body's mesh like the other meshers, tags the body's own source, target and side faces, and is on the MCP mesh tool as hex_extrude.
