Revit二次开发API示例 PathReinforcement是用于在构件路径上定位并布置钢筋的工具
572
2024/11/24
应用程序：PathReinforcement
Revit平台：所有
Revit版本：2011.0
首次发布版本：2008.0
编程语言：C#
技能水平：中等
类别：结构
类型：ExternalCommand
主题：显示PathReinforcement信息。
概要：
此示例演示了如何检索路径加强对象的曲线、剖面和属性。
类：
Autodesk.Revit.UI.IExternalCommand
Autodesk.Revit.DB.Structure.PathReinforcement
Autodesk.Revit.DB.Structure.RebarBarType
Autodesk.Revit.DB.ModelCurve
项目文件：
Command.cs
此文件定义了一个从IExternalCommand继承并实现Execute方法的Command类。类的主要功能是显示主要对话框。
PathReinforcementForm.cs
此文件定义了一个从Form继承的PathReinforcementForm类。该类是包含一个图片框和一个属性网格的主要对话框。图片框用于显示路径加强的曲线，而属性网格用于显示路径加强的属性。
Profile.cs
此文件定义了一个Profile类，用于存储路径加强的几何信息。该类包含一个公共方法“Draw”，用于绘制路径加强的曲线和剖面。
PathReinProperties.cs
此文件定义了一个PathReinProperties类，其中包含路径加强属性。路径加强的属性将显示在PathReinforcementForm的属性网格中。
BarTypeConverter.cs
此文件定义了一个BarTypeConverter类，用于在ElementId和String之间转换类型。
MathTools.cs
此文件定义了一个Vector4和一个Matrix4类，用于在2D和3D之间转换几何数据。
描述：
此示例将从活动文档中获取路径加强，并在对话框中显示其属性。路径加强的曲线将显示在图片
中，其他数据将显示在属性网格中。可以通过路径加强的“曲线”属性获取几何数据，并可以通过“
性”属性获取其他属性。
说明：
1. 打开或新建一个Revit项目，并确保已放置一些路径加强。样例项目文件PathReinforcement.rvt可在示例文件夹中找到。
2. 选择一个路径加强，运行命令，一个窗体将弹出。
3. 所选路径加强的路径和剖面将显示在图片框中：路径以蓝色显示，剖面以红色显示。
4. 路径加强的属性将显示在属性网格中；用户可以通过属性网格更改路径加强的某些参数。
5. 单击“确定”按钮后，路径的更改参数将被更新。
