Per bearing: L = A + margin along the 교축 (s), W = B + margin across it; the underside is the bearing top (block top EL.X + h3); the top tapers from T1 = T + L·|S|/200 at the 시점 side (−s) to T2 = T − L·|S|/200 at the 종점 side, so T1 + T2 = 2T and the volume is L·W·T. Corners follow the bearing row (rowSkew). Tests cover L, W, T1, T2, the underside, the volume and the centring. The model and the 3D do not use it yet.
