━━ 实测约定（都踩过，见 NOTES-probed.md）━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||
|
||||
1. `CreateTransform` 只能走 dispid + `VARIANT(VT_ARRAY|VT_R8)`。
|
||||
传 list / 普通 VARIANT → "服务器出现意外情况"；
|
||||
传 tuple → **不报错但静默返回单位阵**。⇒ 必须回读校验。
|
||||
|
||||
2. ⛔⛔ `ToolsCheckInterference2` **是死的**：在"刀片板体直接穿过底板板体"
|
||||
这种必然干涉的姿态下仍返回 `None` / PComp 0 条。它不抛异常、返回值看着像
|
||||
正常答案 —— 拿它做判据会得出"全程无干涉"的假结论。**改用
|
||||
`IInterferenceDetectionMgr`**（还附带干涉体积）。
|
||||
|
||||
3. `GetInterferenceCount` / `GetInterferences` 在 tlb 里标 invkind=1（方法），
|
||||
但动态派发下必须**当属性取**（不加括号），同 NOTES §9。
|
||||
|
||||
4. 旋转矩阵 `ArrayData[0:9]` 是**列主序**（NOTES §14 原来写的"行主序"是错的）——
|
||||
本脚本用 `validate` 在装配体上现场判定，不写死。
|
||||
|
||||
5. 底板自身就有几十处预存干涉（器件 3D 模型压进板体等），所以**只统计
|
||||
刀片子树 ↔ 底板子树的跨对**，否则信号被淹没。
