应用程序：MultiplanarRebar
Revit平台：结构
Revit版本：2012.0
首次发布版本：2012.0
编程语言：C#
技能水平：高

类型：ExternalCommand
主题：创建多平面钢筋。
摘要：本示例演示API创建多平面钢筋。多平面钢筋的一个用户场景是悬臂梁的加固。本示例是用于加固倾斜悬臂板。
类：
Autodesk.Revit.UI.IExternalCommand
Autodesk.Revit.Creation.Document
Autodesk.Revit.DB.FamilyInstance
Autodesk.Revit.DB.Structure.Rebar
Autodesk.Revit.DB.Structure.RebarShape

Autodesk.Revit.DB.Structure.RebarShapeMultiplanarDefinition
Autodesk.Revit.DB.Structure.StructuralType

Autodesk.Revit.DB.Solid
项目文件：
Command.cs
这是示例的入口点。它实现了IExternalCommand Execute方法。
CorbelFrame.cs
它表示悬臂板的框架，包括梯形剖面和挤压线。可以通过沿着挤压线展开梯形剖面来构建悬臂板。
CorbelReinforcementOptions.cs
此类表示悬臂板的加固选项。选项包括通过UI输入从用户收集的钢筋类型和钢筋数量。
CorbelReinforcementOptionsForm.cs
这个类是一个表单，用于收集用户对悬臂板钢筋创建的选项。
GeometryUtil.cs
此类用于解析给定悬臂板FamilyInstance的几何信息，并根据解析的几何信息最终构造一个CorbelFrame。
SharedParameterUtil.cs
这是一个实用程序类，用于在Revit文档中创建共享参数。它简化了共享参数创建过程。
描述:
1. 本示例将重点关注悬臂板的加固，悬臂板的主体（墙、柱）的加固超出了此范围，除了需要锚定悬臂板箍筋的直钢筋之外。
2. 悬臂板的钢筋包括水平直钢筋、箍筋和一根多平面钢筋。在悬臂板主体中有两根垂直直钢筋用于锚定悬臂板箍筋。
3. 本示例将提供一个简单的UI来收集钢筋创建选项，如钢筋类型和数量。
详细设计：
1. 第一步是悬臂板几何分析：
a)悬臂板是一个族实例，因此可以通过Element.Geometry()获取其几何形状。本示例需要过滤掉悬臂板的梯形面，因此我们必须获取Solid以进行更深入的解析。
b)遍历Solid的所有面以过滤出梯形面，这是整个示例的关键，多平面钢筋形状和所有钢筋的放置都依赖于这个梯形面。
2. 多平面钢筋形状的创建：
钢筋形状由两个直线段组成，因此我们应该创建RebarShapeDefinitionBySegments，然后根据梯形面添加几何约束。为了创建多平面形状，必须创建一个RebarShapeMultiplanarDefinition。最后，我们调用静态方法RebarShape.Create（…）完成钢筋形状的创建。
3. 在悬臂板和其主体中创建钢筋：
a)使用Rebar.CreateFromCurves创建悬臂板水平直钢筋和悬臂板主体的垂直直钢筋。布置规则设置为固定数量，并使用SetLayoutAsFixedNumber方法。
b)使用形状“T1”通过Rebar.CreateFromRebarShape方法创建箍筋，布置规则使用SetLayoutAsFixedNumber方法设置为固定数量。（三角形区域中填充的箍筋单独放置）。Rebar.ScaleToBox用于将箍筋放置在一个精确计算的边界框中。
c)创建多平面钢筋的第一步是创建多平面形状，然后使用Rebar.CreateFromRebarShape方法来创建钢筋。Rebar.ScaleToBoxFor3D()用于将多平面放置在给定的边界框中。根据梯形面计算边界框。
4.挑战:
这个示例的挑战是对钢筋位置的计算。有几个因素需要考虑：
a)钢筋类型-它包含钢筋直径和弯曲半径的定义。
b)悬臂板和其主体的覆盖距离。
c)多平面钢筋形状的平面弯曲直径。
d)在本示例中，我们考虑了钢筋直径和覆盖距离，但是我们不考虑弯曲半径。换句话说，我们将每个弯曲半径视为零。
说明：
1.设置插件文件并让Revit加载此示例。
2.打开示例文件“Reinforce Corbels.rvt”。
3.选择文档中的悬臂板。支持矩形选择；样本将过滤选择集中的悬臂板。
4.如果选择集包含可以通过此示例加固的悬臂板，则会显示一个窗口并让用户输入简单选项。如果选择不满足条件，则会显示一个警告消息，告知发生了什么。
5.单击窗口上的“确定”按钮以加固悬臂板。
6.在Revit UI中检查此示例创建的钢筋。
7.结束。
