u"""把 topshell_v3.py 里「候选映射逐个试」的切除换成「读草图变换 + 先验平面再下刀」。
|
||
|
||
起因（2026-09-13 实测）：东端墙那一刀 Select4 返回 True、选中数 1、选中面 box 也对，
|
||
但 InsertSketch 之后草图却建在了**顶板**上（风口从顶上切穿），靠「切出了东西但不在目标位置」才拦下。
|
||
⇒ 选中数不能证明草图建在哪；**进草图后读 ActiveSketch.ModelToSketchTransform**：
|
||
列主序 M[r][c] = a[3c+r]，s = M·p + t（米）；第 3 行 = 草图法线。
|
||
法线轴 ≠ 目标轴 或 墙面上一点的草图 z ≠ 0 ⇒ 退出重进，三次不成就停手。
|
||
同一个变换顺带给出精确的 uv 映射，不再需要候选法。
