A Merge makes adjacent faces of a body one virtual face in what meshers
take from it (tessellation tags, faces, surfaces, edge and vertex names):
the edges inside it are dropped and the pieces of an edge it leaves are
joined; the B-rep is unchanged. Design::merged applies merges after the
partitions and lists the ones that fail as feature errors.
