Revit二次开发API示例 Route ducts and fittings. 布置管道和配件。

应用程序：AutoRoute

Revit 平台：所有

Revit 版本：2011.0

首次发布于：2010.0

编程语言：C#

技能水平：初级

类别：MEP（机电管道）

类型：ExternalCommand （外部命令）

主题：布置管道和配件。

摘要：此示例演示了如何在基础供气设备和2个端子之间布线一组风管和管件。

相关类:

Autodesk.Revit.DB.Mechanical.MechanicalSystem

Autodesk.Revit.DB.Mechanical.Duct

Autodesk.Revit.DB.FamilyInstance

Autodesk.Revit.DB.Connector

Autodesk.Revit.DB.Document

项目文件：

Command.cs此文件包含从IExternalCommand继承的类Command。它的功能是在一个基本供气设备和2个终端之间布置一组管道和配件。

功能：

-若要创建机械系统，请使用Document.create.NewMechanicalSystem。

-若要定义管线，请首先找到界定所有三个图元的边界框，然后尝试将X轴和Y轴上的中线、四分之一线作为带有一系列风管的主干，这些风管将通过管件和风管连接到图元。

-若要创建风管，请使用Document.create.NewDuct。

-若要创建管件，请使用Document.create.NewElbowFitting和Document.create.NewTeeFitting。

-要在连接器之间建立连接，请使用Connector.ConnectTo

实施：

1.运行命令。（在此之前，您可以移动端子和设备的位置）

2.将自动创建机械系统及其风管工程。
