A seed is matched to a mesher's curve by position (ends and middle within the two tessellations' tolerance), which also orients its bias. Interval assignment holds exact seeds, raises minimums and takes free seeds as goals; an equality, loop minimum or parity it cannot meet with the exact seeds held names them. Seeded curves get the seed's spacing. Extrude and revolve seed cross-section curves and the layers of a level interval; sweep and mapped seed their B-rep edges; cells seed the shared edge once, so both cells keep it and stay conforming.
