u"""在已开着的 EndPlate_v11 上补南侧面 A 组 2 个孔，另存为 v12。
|
||||
|
||||
v11 实测：C 组 2 孔 + 北侧面 A 组 2 孔全部**位置正确**（回读轴线核过），
|
||||
只有南侧面（朝外法线 −y）那一刀 `FeatureCut4 → None`。
|
||||
北侧面（朝外 +y）用的映射 u→x、v→−z 是对的；
|
||||
假设：**朝外 −y 的面上草图 u 轴是镜像的**（u→−x），圆画到了 x=−7.4、落在材料外，
|
||||
没东西可切所以返回 None。
|
||||
|
||||
做法：按候选映射依次试，每刀之后回读「南侧应有的孔」是否出现在
|
||||
x 7.4 / y −1.655~4.345 / z 10、60；对了就停。
|
||||
候选里错误的映射都会把圆画到材料外（x −7.4 或 z −10/−60 处没有料）⇒ 只会返回 None，
|
||||
不会在错位置切出孔 —— 但仍然每步回读、并守住「已有孔不能少」。
