u"""端板 v11 = v10 的几何 + **试着把 A/C 两组螺母孔做出来**。
|
||
|
||
v10 把「肉」给够了（4 根角柱），但孔一直留给 GUI，因为 `FeatureCut4` 在本机
|
||
连续 7 次返回 None。⇒ 本脚本按 NOTES 里**唯一成功过的那个配方**再试一次：
|
||
|
||
✅ 成功的那次：托盘柱顶孔 —— 草图建在**实体的面**上（而且是 z 常量面），沿面法线切。
|
||
⛔ 失败的那些：草图建在**基准面**上（前视/右视）去切。
|
||
|
||
C 组（沿 z，打进角柱顶面 z=72）与那次**构型完全相同**，成功概率最高。
|
||
A 组（沿 y，打进角柱外侧面）是同一招换个面，一并试。
|
||
|
||
⚠ 两条必须守住的纪律：
|
||
1. **不动 v10**。v10 已在总装里验过（干涉 360、贴合 10 组），v11 没通过就原样丢掉。
|
||
2. **判据是圆柱面半径直方图，而且要双向看**：
|
||
· 新增：R2.1 应该 +6（4 个 A + 2 个 C）；
|
||
· **没丢**：R1.7 仍是 4（风扇螺孔）、R30 仍是 1（风口）。
|
||
NOTES 记过一次面上草图的异常拉伸**把已有 8 个孔全吞掉**，只看"新增"是抓不到的。
|
||
|
||
局部坐标（西端板；装配 x = 本地 x − 38.4，z 与装配同值）：
|
||
· 角柱 本地 x 2.4~12.4（中心 **7.4** = 装配 −31）、通高 z 0~72
|
||
南柱 y −1.655~6.345（中心 **2.345**）／北柱 y 96.345~104.345（中心 **100.345**）
|
||
· C 组 2 孔：柱顶面 z=72，(x,y) = (7.4, 2.345) / (7.4, 100.345)，Ø4.2 深 6
|
||
· A 组 4 孔：柱外侧面 y=−1.655 与 y=104.345，(x,z) = (7.4, 10) / (7.4, 60)，Ø4.2 深 6
