+# 任务描述
+基于二维导航地图的路径构建功能开发：
+1. 通过交互控件选择通道模型
+2. 在二维地图上设置起点、终点、路径点（在通道表面上）
+3. 用直线连接路径点，绘制可视化路径
+4. 支持路径规划结果的导入和导出（DELMIA兼容）
+5. 显示点的坐标并支持手动修改
+
+# 项目概述
+在现有Navisworks 2017物流插件基础上，扩展路径构建功能。采用二维导航地图方案简化3D路径规划的用户交互，提高操作便利性和坐标精确度。为后续碰撞检测功能做准备。
+
+---
+*以下部分由 AI 在协议执行过程中维护*
+---
+
+# 分析 (由 RESEARCH 模式填充)
+基于现有插件架构分析：
+- 已有CategoryAttributeManager.cs处理物流分类属性
+- 已有VisibilityManager.cs处理可见性控制  
+- MainPlugin.cs提供UI框架，可扩展第三个功能区域
+- Navisworks 2017 API支持Graphics绘制、ModelItem选择、坐标转换
+- 需要创建独立的2D地图窗口简化路径点设置交互
+
+技术约束：
+- Windows 7 + .NET Framework 4.6.2环境
+- Navisworks 2017 API限制
+- 需要COM API支持某些高级功能
+
+# 提议的解决方案 (由 INNOVATE 模式填充)
+方案选择：基于现有架构的扩展式设计 + 独立2D地图窗口
+
+核心技术路径：
+1. **2D导航地图方案**：创建独立WinForms窗口显示通道俯视图，通过鼠标点击设置路径点
+2. **坐标转换系统**：实现2D屏幕坐标到3D世界坐标的精确转换
+3. **直线路径连接**：使用Graphics API在3D视图中绘制路径线条
+4. **结构化数据导出**：支持XML/JSON/CSV格式，DELMIA兼容
+
+优势：
+- 用户体验：2D地图比3D视图更直观，操作更精确
+- 技术实现：延续现有设计模式，开发风险低
+- 数据准备：为后续碰撞检测提供理想的路径数据基础
+
+# 实施计划 (由 PLAN 模式生成)
+
+## 核心技术架构
+**模块划分**：
+- PathPlanningManager.cs：路径规划核心业务逻辑
+- NavigationMapWindow.cs：2D导航地图窗口（WinForms）
+- CoordinateConverter.cs：2D/3D坐标系统转换工具
+- PathDataManager.cs：路径数据管理和导入导出
+- PathVisualizer.cs：3D路径可视化绘制
+
+**数据结构**：
+```csharp
+public class PathPoint
+{
+    public Point3D Position { get; set; }
+    public string Name { get; set; }
+    public PathPointType Type { get; set; } // StartPoint, EndPoint, WayPoint
+    public DateTime CreatedTime { get; set; }
+}
+
+public class PathRoute
+{
+    public List<PathPoint> Points { get; set; }
+    public string Name { get; set; }
+    public double EstimatedTime { get; set; }
+    public List<ModelItem> AssociatedChannels { get; set; }
+}
+```
+
+实施检查清单：
+1. 创建路径规划数据结构类
+2. 创建坐标转换工具类  
+3. 创建2D导航地图窗口
+4. 创建路径规划管理器
+5. 创建3D路径可视化组件
+6. 创建路径数据管理器
+7. 集成到MainPlugin用户界面
+8. 实现通道选择和筛选功能
+9. 添加路径验证和优化功能
+10. 完善错误处理和用户体验
