+## 8. 菜单命令 → 实体 → 工具 对照表
+
+来源：`c:\ShangHuaSoft\Envi3D-2026-M\sys\*.mnu`（8 个文件、674 条命令、GBK 编码）。
+做法：解析 `ID_xxx [四字说明]命令` → 用命令名在源码里找注册的 handler
+（`ADD_CMD` / `acedRegCmds->addCommand`）→ 在 handler（含一层直接调用）里找 `new AecDbXxx`
+→ 得到"会新建实体的命令"共 74 条、涉及 44 个实体类。
+
+已实现的实体：管道/墙/板/柱/梁/爬梯（每类一个 `add_*` + 一个 `update_*`）。
+其余实体的创建参数还没梳理（多数要读对话框），标"（未实现）"，
+要补的话照 `add_aec_climb_stair` 的写法：命令实现里抄建模序列 → 抽出参数 → 加工具。
