A partition intersects the body with a box on each side of the plane as large as the body itself. SolidCraft's split_by_plane uses boxes several times larger, and its boolean then put the cut up to 1.8 um off the plane on the enclosure's air, so the cut faces were not recognized and the cells did not close. A plane along a face of a body it cuts, or a cell whose boundary does not tessellate into one a mesher takes (a cut through a hole's axis), is a warning naming the partition, the body and where.
