1.获取Revit中打开的所有的View(视图)

using System;
using System.Collections.Generic;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI.Selection;
namespace 插件
{[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)]public class Command:IExternalCommand{/// <summary>/// 获取所有打开的视图并返回视图名称/// </summary>/// <param name="uidoc"></param>/// <returns></returns>private string GetOPenViews(UIDocument uidoc){string info = null;IList<UIView> views = uidoc.GetOpenUIViews();foreach(UIView view in views){info += uidoc.Document.GetElement(view.ViewId).Name+"\n";}return info;}public Result Execute(ExternalCommandData commandData,ref string message,ElementSet elementSet){UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;Selection selection = uidoc.Selection;try{string res = GetOPenViews(uidoc);TaskDialog.Show("OpenViews", $"{res}");return Result.Succeeded;}catch(Exception ex){TaskDialog.Show("Error Info", $"{ex.Message}");return Result.Failed;}}}
}

2.在不打开Revit的情况下读取rvt文件数据

在Revit插件中可以在后台打开rvt文件，并且访问他的数据，但是这个数据读取时依赖于Revit软件的。
就是说必须要在Revit打开的情况下，运行一个插件，在插件代码里读取rvt 的信息
我准备了一个机电测试文件，这个项目文件里面一共画了三个构建：一个长度为8800mm的风管，一个长度为6600mm的水管和一个桥架

下面的例子实现了打开一个rvt文件，并且过滤其中的风管类型的构建，并且获取风管实例的长度，结果确实是8800mm

using System;
using System.Collections.Generic;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI.Selection;
using Autodesk.Revit.DB.Mechanical;
using Autodesk.Revit.DB.Plumbing;
using Autodesk.Revit.DB.Electrical;
namespace 插件
{[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)]public class Command:IExternalCommand{public Result Execute(ExternalCommandData commandData,ref string message,ElementSet elementSet){UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;Selection selection = uidoc.Selection;Autodesk.Revit.ApplicationServices.Application app = commandData.Application.Application;Document _doc = app.OpenDocumentFile(@"D:\revit development project\Revit开发\机电测试.rvt");try{FilteredElementCollector filter = new FilteredElementCollector(_doc);filter.OfCategory(BuiltInCategory.OST_DuctCurves).WhereElementIsNotElementType();foreach(Element elem in filter){LocationCurve lc = elem.Location as LocationCurve;TaskDialog.Show("Info",$"风管的长度={lc.Curve.Length*304.8}");}return Result.Succeeded;}catch(Exception ex){TaskDialog.Show("Error Info", $"{ex.Message}");return Result.Failed;}}}
}

3.获取元素的材质信息

}

5.编辑族参数(没有成功，后期会更新)

注意:只有载入的族才是可以修改的

using System;
using System.Collections.Generic;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI.Selection;
using Autodesk.Revit.DB.Mechanical;
using Autodesk.Revit.DB.Plumbing;
using Autodesk.Revit.DB.Electrical;
namespace 插件
{[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)][Autodesk.Revit.Attributes.Regeneration(RegenerationOption.Manual)][Autodesk.Revit.Attributes.Journaling(JournalingMode.UsingCommandData)]public class Command : IExternalCommand{public readonly double unit = 304.8;public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet){UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;Selection selection = uidoc.Selection;Reference reff = selection.PickObject(ObjectType.Element);Element elem = doc.GetElement(reff);//返回familySymbol的IdElementId id = elem.GetTypeId();FamilySymbol fmSymbol = doc.GetElement(id) as FamilySymbol;// 返回编辑族的DocumentDocument fmDoc = doc.EditFamily(fmSymbol.Family);// 得到FamilyManager,关于族参数的操作都在里面FamilyManager manager = fmDoc.FamilyManager;IList<FamilyParameter> parameters = manager.GetParameters();string info = string.Empty;for(int i=0;i<parameters.Count;i++){info += parameters[i].Definition.Name + "\n";}TaskDialog.Show("Parameter",info);Transaction ts = new Transaction(doc, "创建墙体");ts.Start();//  manager.RemoveParameter(parameters[-4]);manager.AddParameter("gender", BuiltInParameterGroup.PG_IDENTITY_DATA, ParameterType.Text, false);ts.Commit();fmDoc.LoadFamily(doc, new Opt());return Result.Succeeded;}}public class Opt : IFamilyLoadOptions{public bool OnFamilyFound(bool familyInUse, out bool overwriteParameterValues){overwriteParameterValues = true;return true;}public bool OnSharedFamilyFound(Family sharedFamily, bool familyInUse, out FamilySource source, out bool overwriteParameterValues){throw new NotImplementedException();}}
}

6.访问墙体结构层信息

using System;
using System.Collections.Generic;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI.Selection;
using Autodesk.Revit.DB.Mechanical;
using Autodesk.Revit.DB.Plumbing;
using Autodesk.Revit.DB.Electrical;
namespace 插件
{[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)][Autodesk.Revit.Attributes.Regeneration(RegenerationOption.Manual)][Autodesk.Revit.Attributes.Journaling(JournalingMode.UsingCommandData)]public class Command : IExternalCommand{public readonly double unit = 304.8;public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet){UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;Selection selection = uidoc.Selection;Reference reff = selection.PickObject(ObjectType.Element, "please select a wall");Wall wall = doc.GetElement(reff) as Wall;string info = string.Empty;CompoundStructure compoundStructure = wall.WallType.GetCompoundStructure();foreach(CompoundStructureLayer item in compoundStructure.GetLayers()){if (item.MaterialId == ElementId.InvalidElementId) continue;Material m = doc.GetElement(item.MaterialId) as Material;if (m == null) continue;info += m.Name + "\n";}TaskDialog.Show("墙体结构材质",info);return Result.Succeeded;}}
}

7.取消选中元素

using System;
using System.Collections.Generic;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI.Selection;
using Autodesk.Revit.DB.Mechanical;
using Autodesk.Revit.DB.Plumbing;
using Autodesk.Revit.DB.Electrical;
using System.Threading;
namespace 插件
{[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)][Autodesk.Revit.Attributes.Regeneration(RegenerationOption.Manual)][Autodesk.Revit.Attributes.Journaling(JournalingMode.UsingCommandData)]public class Command : IExternalCommand{public readonly double unit = 304.8;public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet){UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;Selection selection = uidoc.Selection;IList<Reference> reffs = selection.PickObjects(ObjectType.Element);string info = string.Empty;foreach(var item in reffs){info += doc.GetElement(item).Name + "\n";}info += "点击确认三秒钟以后会自动取消选中地元素";TaskDialog.Show("Title", info);Thread.Sleep(3 * 1000);// 方法1elementSet.Clear();// 方法2selection.SetElementIds(new List<ElementId>());return Result.Succeeded;}}
}

8.选中元素

2015以后的版本都用selection.SetElementIds(List ids)这个方法来设置元素选中。

using System;
using System.Collections.Generic;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI.Selection;
using Autodesk.Revit.DB.Mechanical;
using Autodesk.Revit.DB.Plumbing;
using Autodesk.Revit.DB.Electrical;
using System.Threading;
namespace 插件
{[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)][Autodesk.Revit.Attributes.Regeneration(RegenerationOption.Manual)][Autodesk.Revit.Attributes.Journaling(JournalingMode.UsingCommandData)]public class Command : IExternalCommand{public readonly double unit = 304.8;public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet){UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;Selection selection = uidoc.Selection;Reference reff = selection.PickObject(ObjectType.Element);Element elem = doc.GetElement(reff);selection.SetElementIds(new List<ElementId>() { elem.Id});TaskDialog.Show("选择", "已经选中");Thread.Sleep(2*1000);// 传入一个空的列表，即取消选中selection.SetElementIds(new List<ElementId>());return Result.Succeeded;}}
}

9获取元素的几何信息

Revit中元素的几何信息可以通过get_Geometry(Options)方法获取，这个方法返回一个GeometryElement类型的值，GeometryElement里面包含了这个元素所有的GeometryObject
这个函数需要传入一个Options的参数，Options有一个默认无参数的构造器，Options类有下面几个属性可以设置：

属性	说明
ComputeReferences	这是一个布尔值，如果是true,那么返回的Reference不为空，默认为false
IncludeNonVisibleObjects	设置是否包含不可见的几何
DetailLevel	对应视图的详细程度
IsReadOnly	是否只读
View	返回这个视图中可见的几何

注意：获取元素几何信息一般分为系统族和载入族来考虑，如果是系统族使用XX.get_Geometry(opt)获取到的就是实体(Solid)

如果族是载入族，要看是否是剪切过的族，如果是剪切过的族，那么方法与系统族类似
如果不是剪切过的族，那么

通过XX.get_Geometry(opt)获取到GeometryElement
再从GeometryElement获取到GeometryInstance,再从GeometryInstance.GetInstanceGeometr()或者GeometryInstance.GetSymbolGeometry()获取Solid进行操作

GeometryObject有下面的几个子类:

Autodesk.Revit.DB.XX.Curve
Autodesk.Revit.DB.XX.Face
Autodesk.Revit.Db.XX.Edge
Autodesk.Revit.DB.XX.GeometryElement
Autodek.Revit.DB.XX.GeometryInstance
Autodesk.Revit.DB.XX.Mesh
Autodesk.Revit.DB.XX.Point
Autodesk.Revit.DB.XX.PolyLine
Autodesk.Revit.DB.XX.Profile
Autodesk.Revit.DB.XX.Solid

下面的代码实现了获取一个系统族(墙)的底面积和一个载入族(柱子)的底面积 ```csharp using System; using System.Collections.Generic; using Autodesk.Revit.UI; using Autodesk.Revit.DB; using Autodesk.Revit.Attributes; using Autodesk.Revit.UI.Selection; using Autodesk.Revit.DB.Mechanical; using Autodesk.Revit.DB.Plumbing; using Autodesk.Revit.DB.Electrical; using System.Threading; namespace 插件 { [Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)] [Autodesk.Revit.Attributes.Regeneration(RegenerationOption.Manual)] [Autodesk.Revit.Attributes.Journaling(JournalingMode.UsingCommandData)] public class Command : IExternalCommand { public readonly double unit = 304.8;

    public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet){UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;Selection selection = uidoc.Selection;Options opt = new Options{ComputeReferences = true,DetailLevel = ViewDetailLevel.Fine,IncludeNonVisibleObjects = false};// wallReference reff = selection.PickObject(ObjectType.Element, "选择一堵墙");Wall wall = doc.GetElement(reff) as Wall;GetWallBottomFaceAndComputeArea(wall, opt);// columnReference refColumn = selection.PickObject(ObjectType.Element, "请选择一个柱子");FamilyInstance instance = doc.GetElement(refColumn) as FamilyInstance;GetColumnBottomFaceAndComputeArea(instance, opt);return Result.Succeeded;}/// <summary>/// 获取一个没有剪切的柱子实体最下面的面，并且输出面积/// </summary>/// <param name="fmInstance"></param>/// <param name="opt"></param>public void GetColumnBottomFaceAndComputeArea(FamilyInstance fmInstance,Options opt){GeometryElement geoElem = fmInstance.get_Geometry(opt);Face face = null;foreach(GeometryObject obj in geoElem){if(obj is Solid){Solid solid = obj as Solid;if(solid.Faces.Size>0){face = FindBottomFace(solid);}}else if(obj is GeometryInstance){GeometryInstance gmInstance = obj as GeometryInstance;// 获取实例的solidGeometryElement geoElem1 = gmInstance.GetInstanceGeometry();// 获取族类型的solid//GeometryElement geoElem1 = gmInstance.GetSymbolGeometry();foreach(GeometryObject obj2 in geoElem1){if(obj2 is Solid){Solid solid = obj2 as Solid;if(solid.Faces.Size>0){face = FindBottomFace(solid);}}}}}TaskDialog.Show("柱子的底面积", face.Area.ToString());}/// <summary>/// 获取墙体实体最下面的面，并且输出面积/// </summary>/// <param name="wall"></param>/// <param name="opt"></param>public void GetWallBottomFaceAndComputeArea(Wall wall,Options opt){GeometryElement geoElem = wall.get_Geometry(opt);foreach(GeometryObject obj in geoElem){Solid solid = obj as Solid;// 排除获取到的不是实体和获取到的无效实体if(solid!=null && solid.Faces.Size>0){Face face = FindBottomFace(solid);TaskDialog.Show("面积", face.Area.ToString());}}}/// <summary>/// 找出一个实体最下面的一个面/// </summary>/// <param name="solid"></param>/// <returns></returns>public Face FindBottomFace(Solid solid){foreach(Face face in solid.Faces){PlanarFace face1 = face as PlanarFace;if(face!=null){if(face1.FaceNormal.X<0.01 && face1.FaceNormal.Y<0.01 && face1.FaceNormal.Z<0){return face;}}}return null;}
}

}

### 10绑定命令——传递创建门命令
```csharp
using System;
using System.Collections.Generic;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI.Selection;
using Autodesk.Revit.DB.Mechanical;
using Autodesk.Revit.DB.Plumbing;
using Autodesk.Revit.DB.Electrical;
using System.Threading;
namespace 插件
{[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)][Autodesk.Revit.Attributes.Regeneration(RegenerationOption.Manual)][Autodesk.Revit.Attributes.Journaling(JournalingMode.UsingCommandData)]public class Command : IExternalCommand{public readonly double unit = 304.8;public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet){UIApplication uiapp = new UIApplication(commandData.Application.Application);UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;Selection selection = uidoc.Selection;// 传递创建门的命令CommandTest(uiapp);return Result.Succeeded;}private void CommandTest(UIApplication uiapp){RevitCommandId CommandId = RevitCommandId.LookupPostableCommandId(PostableCommand.Door);if(uiapp.CanPostCommand(CommandId)){uiapp.PostCommand(CommandId);}}}
}

10 预览Revit视图的控件

Command类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;
using Autodesk.Revit.Attributes;
namespace 插件2
{[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)][Autodesk.Revit.Attributes.Regeneration(RegenerationOption.Manual)][Autodesk.Revit.Attributes.Journaling(JournalingMode.UsingCommandData)]class Command:IExternalCommand{public Result Execute(ExternalCommandData commandData,ref string message,ElementSet elementSet){UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;PreWindow window = new PreWindow(commandData.Application.Application);window.Show();return Result.Succeeded;}}
}

界面的XMAL

}

效果如下：

11 对元素的基本操作

Revit中可以通过API对元素进行复制，移动，旋转，镜像等基本操作。这些功能都可以通过ElementTransformUtils类来实现，下面是简单的示例

using System;
using System.Collections.Generic;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI.Selection;
using Autodesk.Revit.DB.Mechanical;
using Autodesk.Revit.DB.Plumbing;
using Autodesk.Revit.DB.Electrical;
using System.Threading;
namespace 插件
{[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)][Autodesk.Revit.Attributes.Regeneration(RegenerationOption.Manual)][Autodesk.Revit.Attributes.Journaling(JournalingMode.UsingCommandData)]public class Command : IExternalCommand{public readonly double unit = 304.8;public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet){UIApplication uiapp = new UIApplication(commandData.Application.Application);UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;Selection selection = uidoc.Selection;#region 移动TaskDialog.Show("Move", "下面请选择一个墙体，这个墙体将会向右移动1000mm");Wall wall = doc.GetElement(selection.PickObject(ObjectType.Element)) as Wall;using (Transaction ts = new Transaction(doc, "Move")){ts.Start();ElementTransformUtils.MoveElement(doc, wall.Id, new XYZ(1000 / unit, 0, 0));ts.Commit();}#endregion#region 复制TaskDialog.Show("Copy", "选择一个墙体，这个墙体上方1000mm处复制一个新的墙体");Wall wall1 = doc.GetElement(selection.PickObject(ObjectType.Element)) as Wall;using (Transaction ts = new Transaction(doc, "Copy")){ts.Start();ElementTransformUtils.CopyElement(doc, wall1.Id, new XYZ(0, 1000 / 304.8, 0));ts.Commit();}#endregion#region 旋转TaskDialog.Show("Rotate", "选择一个墙体，将会把这个墙体顺时针旋转45度");Wall wall2 = doc.GetElement(selection.PickObject(ObjectType.Element)) as Wall;using (Transaction ts = new Transaction(doc, "Rotate")){ts.Start();XYZ pt1 = ((wall2.Location as LocationCurve).Curve as Line).GetEndPoint(0);Line line = Line.CreateBound(new XYZ(pt1.X, pt1.Y, 0), pt1);ElementTransformUtils.RotateElement(doc, wall2.Id, line, 45);ts.Commit();}#endregion#region 镜像TaskDialog.Show("Mirror", "选择一个墙体,再点击两个点，将会把这个墙体以两个点连成的直线为轴镜像一个新的墙体");Wall wall3 = doc.GetElement(selection.PickObject(ObjectType.Element)) as Wall;using (Transaction ts = new Transaction(doc, "Mirror")){ts.Start();XYZ pt1 = selection.PickPoint("请选择镜像轴的第一个端点");XYZ pt2 = selection.PickPoint("请选择镜像轴的第二个端点");XYZ origin = (pt1 + pt2)/2;XYZ pt3 = new XYZ(origin.X, origin.Y, origin.Z + 100);Plane plane = Plane.CreateByThreePoints(pt1, pt2, pt3);ElementTransformUtils.MirrorElement(doc, wall3.Id, plane);ts.Commit();}#endregionreturn Result.Succeeded;}}
