On ③ the members, the ground and the blinding concrete are drawn at half opacity without depth writes, so the bars show
through. Outside ③ each part returns to its own opacity. Rebar colours are shaded to 0.8 and slightly glossier so they
read through the members. Approved 2026-10-23.

The stair bars in the 철근표 and the 3D model, and the 3D bottom and column bars, were built with the default fck,
so a changed fck did not reach them. buildRebar3D now takes the material, and a material change rebuilds the scene.

- The 3D model of ③ draws each bar family from the rebar modules (coping top and
bottom bars, shear loops, side bars, column bars and ties, footing B1–B8, bearing
S1/S2) and names every bar as its 철근표 number.
- A table row click highlights the bar in 3D (the others dim); a click on a 3D bar
selects its row in the table and sets the member tab. Drags still rotate.
- The rebar is shown only on ③. Not drawn yet: C14, C15/C16, B9–B12, the couplers,
and the bars of a bent coping.
- Tests: family names and counts (P1 46), highlight behaviour.
