Revit二次开发API示例 PathOfTravel是一种分析工具，用于计算建筑空间内的可行路径

应用程序：PathOfTravel

Revit平台：建筑

Revit版本：2020.0

首次发布版本：2020.0

编程语言：C#

技能水平：中等

类别：元素，注释，视图

类型：ExternalCommand

主题：创建行进路径

概要：此示例演示了如何从平面视图中的房间到门创建PathOfTravel元素。

类：

Autodesk.Revit.UI.IExternalCommand

Autodesk.Revit.DB.Creation.Document

Autodesk.Revit.DB.Analysis.PathOfTravel

Autodesk.Revit.DB.Architecture.Room

 Autodesk.Revit.DB.Architecture.Door

项目文件：

Command.cs

它包含从接口IExternalCommand继承并实现Execute方法的Command类。执行显示在CreateForm.cs中定义的对话框。

CreateForm.cs

此文件包含一个Form类，其中包含三个单选控件，允许三种不同的PathOfTravel创建方法。

描述：

此示例提供以下功能。

- 自动计算用于路径起点的房间中心和角点。

- 当选择路径到单个门的选项时，允许用户选择要用于路径终点的门。

- 自动在所选的房间和门元素之间创建PathOfTravel元素。

说明：

打开Revit应用程序并执行命令。

1. 创建一些房间和出口门。

2. 打开一个可见所创建元素的平面视图。

3. 执行外部命令。在对话框中，选择一个选项创建路径。单击确定后，路径将被创建并显示在视图中。
