Revit二次开发API示例 Create or retrieve boundary conditions. 创建或检索边界条件。
719
2024/09/29
应用程序：边界条件
Revit平台：结构
Revit版本：2011.0
首次发布用于：9.1
编程语言：C#
技能等级：高
类别：结构
类型：外部命令
主题：创建或检索边界条件
摘要：此示例显示如何获取BoundaryConditions的参数或创建BoundaryConditions。
相关类:
Autodesk.Revit.UI.IExternalCommand
Autodesk.Revit.DB.BoundaryConditions
项目文件：
Command.cs这是主DLL源文件。它包含实现接口IExternalCommand的类Command。
BoundaryConditionsData.cs此文件包含类BoundaryConditionsData，该类准备所需的数据（选定的图元类型及其BC信息）并创建Boundary Conditions。
BCProperties.cs此文件包含三个枚举（BCType、BCState和BCTranslationRotation）和两个类（BCTypeAttribute、BCProperties）。他们为包含在BoundaryConditionsForm中的PropertyGrid准备数据。
UnitConversion.cs此文件包含一个结构ConversionValue和一个类ConversionValue。该结构定义了显示值和内部值之间的转换规则。类是一个值转换字典，它存储一些单位及其对应的ConversionValue。
功能：
-只选择一个结构元素。
-如果所选择的元素具有边界条件，则呈现边界条件（BC）的参数。用户还可以使用其他有效值设置这些参数。
-在列表框中列出主机为所选元素的BC的所有Id。
-根据选择的BC Id，将显示相关的BC Type、State和X、Y、Z平移/旋转。
-不允许用户更改BC类型。
-用户可以将BC的“状态”设置为“固定”、“锁定”、“滚动”或“用户”（当选择不同的值时，X、Y或Z平移/旋转应根据Revit主程序UI进行相应的更改）。
-如果选择“用户”作为当前状态，则可以将X、Y或Z平移/旋转设置为“固定”、“释放”或“弹簧”。
-如果为X、Y或Z平移/旋转选择了“弹簧”，则可以输入正值作为“弹簧模量”（为用户显示值的单位）。
-如果所选元素没有BC，则创建一个BC。
-根据所选元素将“BC类型”设置为“点”、“线”或“区域”。（梁/墙/墙基础有BC线；柱/支撑有BC点；板/基础板有BC面积）
-其他初始参数设置为固定。
-用户可以更改除BC类型之外的所有参数值（参考最后一点的详细信息）
-当用户单击“确定”按钮时，将更新现有BC或创建新BC。
-我们应该使用Autodesk.Revit.Creation.Document的NewPointBoundaryConditions、NewLineBoundaryConditions和NewAreaBoundary条件方法来创建BC
实施：
1.打开Revit Structure并绘制一个梁。
2.选择梁并运行样本。
3.在窗体中的PropertyGrid控件中选择属性值。
4.在示例的主UI中，单击“确定”按钮。
5.返回Revit主程序，您可以看到在选定梁上创建了一条线“边界条件”。
其他：
-我们提供了四个附加文件（边界条件Pinned.rfa、边界条件Fixed.rfa、边界条件Roller.rfa和边界条件User.rfa）。它们是边界条件的族文件。如果无法绘制任何边界条件，请先载入这些族。然后在“设置”菜单->“结构设置”->“边界条件设置”中为“边界条件”设置族符号。
-只有以下结构元素可以具有BC：
柱/支撑/独立基础/梁/墙/墙基/板/基础板
