u"""给外壳件加**外轮廓圆角**（用户 2026-09-13 要求）。v2 重写。
|
||||
|
||||
⛔ v1 失败的真因（不是 API 坏了）：
|
||||
最小实验（纯长方体 12 条边）倒 4 条竖边 → 成功、直方图 `{3.0: 4}`。
|
||||
但真实零件上：托盘 60 条边里选了 12 条、端板 34 条里选了 8 条，
|
||||
`FeatureFillet3` 一律返回 **None**。
|
||||
共同点是**选中的边里混进了做不出来的**：
|
||||
· 托盘：USB-C 缺口的内角边 —— 缺口只有 4.2 深，R3 在窄槽内角会自相交；
|
||||
· 端板：L 脚与板面的交线 —— 同理超出可行范围。
|
||||
SolidWorks 对这种"整批里有一条做不出"的情况**整批放弃**，还不报错。
|
||||
|
||||
✅ v2 的三条对策：
|
||||
1. **只倒外轮廓的角**：按实体包围盒筛，边的两个端点必须都落在包围盒的角上，
|
||||
这样自动排除所有内部缺口/开口/台阶产生的边。
|
||||
2. **逐条单独倒**：一条失败不拖垮其余，且能精确报出是哪条边做不出来。
|
||||
3. **失败自动降半径**：R3 → R2 → R1.5 → R1 依次重试。
|
||||
|
||||
判据仍是**圆柱面半径直方图**（包围盒对圆角没有分辨力）。
|
||||
|
||||
用法：python add_fillets.py <零件文件名> [半径] [轴]
