u"""北侧板 v3 —— 跟着 15 mm 分风腔加长（2026-09-13）。
|
||
|
||
与 v2 的差别同南板 v4：长度 152.8 → **175.0**（x −38.4~136.4）、
|
||
A 组螺丝孔挪到端板角柱中心 **x −31/129，z 10/60**（旧的 x −13.70/111.70 打在空气里）。
|
||
两个开口（J33 应急排针、J26/J27 风扇座出线）对准的是底板上的座子，座子没动 ⇒ 位置不动。
|
||
|
||
⛔ 竖板、法线沿 y ⇒ 上视基准面，草图 (u,v) → 模型 (x, −z)。
|
||
⛔ 画草图前 `sm.AddToDB = True`。
