Revit2016 二次开发笔记1.选中图元1.1事先选择某类图元（Wall）Autodesk.Revit.UI.UIApplication revit = commandData.Application;ElementSet collection = new ElementSet();ElementSet selWall = new ElementSet();foreach (ElementId elementId in revit.ActiveUIDocument.Selection.GetElementIds()collection.Insert(revit.ActiveUIDocument.Document.GetElement(elementId); /选中的原件foreach (Element ele in sel)Wall wall = ele as Wall; /如果为墙if (wall !=null)SelWal.Insert(ele);1.2.通过交互方式1.2.1用矩形框选择图元所用方法：PickElementsByRectangle()using System.Collections.Generic; /声明引用命名空间，IlistUIDocument uidoc = commandData.Application.ActiveUIDocument;ElementSet collector = new ElementSet();IList elemList = uidoc.Selection.PickElementsByRectangle();/矩形框的应用string info = 所选图元：;foreach (Element elem in elemList)collector.Insert(elem);info += nt + elem.ToString();TaskDialog.Show(Choose Items, info);return Result.Succeeded;1.2.2用点击选择图元所用方法：PickObject(ObjectType.Element)using Autodesk.Revit.UI.Selection; /声明引用命名空间，ObjectTypeUIDocument uidoc = commandData.Application.ActiveUIDocument;Reference hasPickOne = uidoc.Selection.PickObject(ObjectType.Element);Element elem = uidoc.Document.GetElement(hasPickOne.ElementId);string info = 所选图元：;info += nt + elem.GetType().ToString();TaskDialog.Show(Revit, info);还存在其它用法：Selection.PickObject (ObjectType, String) /string 为提示PickObjects (ObjectType) /允许选择多个元素1.2.3选择及过滤UIDocument uidoc = commandData.Application.ActiveUIDocument;ISelectionFilter selFilter = new MassSelectionFilter();IList eList = uidoc.Selection.PickElementsByRectangle(selFilter) as IList;string info = 选择了以下的墙：;foreach(Element elem in eList)info += nt + elem.Name;TaskDialog.Show(Revit, info);return Result.Succeeded;public class MassSelectionFilter : ISelectionFilterpublic bool AllowElement(Element elem)return elem is Wall; /选择了墙public bool AllowReference(Reference reference, XYZ position)throw new NotImplementedException();/ 第二个条件2.加载族并创建实例UIApplication m_application;UIDocument m_document;m_application = commandData.Application;m_document = m_application.ActiveUIDocument;2.1.加载族1) m_document .Document.LoadFamilySymbol (FullPath, symbolName, out loadedfamilySymbol);2) m_document .Document.LoadFamily (FullPath, out loadedfamily);第一种用来加载族类型，第二种用来加载族，返回的loadfamily和loadfamilysymbol 可以随后用来创建族实例2.2创建族实例创建族实例将经过：1）选择一个平面，建立一个工作平面2）选择一个点放置族实例2.1选择平面Reference faceRef = m_document.Selection.PickObject(ObjectType.Face, new PlanarFaceFilter(m_document.Document), Please pick a planar face to set the work plane. ESC for cancel.);GeometryObject geoObject = m_document.Document.GetElement(faceRef).GetGeometryObjectFromReference(faceRef); PlanarFace planarFace = geoObject as PlanarFace;/判断选择为平面的类public class PlanarFaceFilter : ISelectionFilter / Revit document. Document m_doc = null; / Constructor the filter and initialize the document. public PlanarFaceFilter(Document doc) m_doc = doc; / Allow all the element to be selected public bool AllowElement(Element element) return true; / Allow planar face reference to be selectedpublic bool AllowReference(Reference refer, XYZ point)GeometryObject geoObject = m_doc.GetElement(refer).GetGeometryObjectFromReference(refer);return geoObject != null & geoObject is PlanarFace;2.2创建工作平面SketchPlane faceSketchPlane = CreateSketchPlane(planarFace.FaceNormal, planarFace.Origin);if (faceSketchPlane != null)/ 对模型进行操作必须新建 Transaction 事件Transaction changeSketchPlane = new Transaction(m_document.Document, Change Sketch Plane.);changeSketchPlane.Start(); m_document.Document.ActiveView.SketchPlane = faceSketchPlane; m_document.Document.ActiveView.ShowActiveWorkPlane(); changeSketchPlane.Commit();/创建工作平面的子方法internal SketchPlane CreateSketchPlane(Autodesk.Revit.DB.XYZ normal, Autodesk.Revit.DB.XYZ origin)/ First create a Geometry.Plane which need in NewSketchPlane() method Plane geometryPlane = m_application.Application.Create.NewPlane(normal, origin);/ Then create a sketch plane using the Geometry Plane Transaction createSketchPlane = new Transaction(m_document.Document, Create a sketch plane.); createSketchPlane.Start(); SketchPlane plane = SketchPlane.Create(m_document.Document, geometryPlane); createSketchPlane.Commit(); return plane;2.3 选择一个点并创建实例/ Pick point from current work plane with snaps.ObjectSnapTypes snapType = ObjectSnapTypes.Centers | ObjectSnapTypes.Endpoints | ObjectSnapTypes.Intersections| ObjectSnapTypes.Midpoints | ObjectSnapTypes.Nearest | ObjectSnapTypes.WorkPlaneGrid;XYZ point = m_document.Selection.PickPoint(snapType, Please pick a point to place component.);Transaction LoadAndCreat = new Transaction(m_document.Document, Load a Family.);LoadAndCreat.Start(); / 对模型进行操作必须新建 Transaction 事件/加载族并创建实例FamilySymbol loadedfamilySymbol = null;string directory = C:UsersAdministratorDesktopRevitProgramFamily;string symbolName = 测斜管;trym_document.Document.LoadFamilySymbol(string.Format(01.rfa,directory,symbolName ) , symbolName , out loadedfamilySymbol);catch (Exception e)message = e.Message;return Result.Failed;if (null = loadedfamilySymbol)TaskDialog.Show(Revit, Cant load the prepared rfa.);return Result.Failed;/创建族实例CreatePointFamilyInstance(point, loadedfamilySymbol, StructuralType.NonStructural);LoadAndCreat.Commit(); /子事件结束/创建族实例的方法public bool CreatePointFamilyInstance(XYZ location,FamilySymbol symbol,StructuralType structuralType)if (!symbol.IsActive)symbol.Activate();FamilyInstance instance = m_document.Document.Create.NewFamilyInstance(location, symbol, structuralType);List instanceId = new List();instanceId.Add(instance.Id);m_document.Selection.SetElementIds(instanceId); /已经在选择集里return true;3.用过滤器统计传感器3.1通过族类型名称查找族实例/用到了慢过滤器：FamilyInstanceFilterUIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;FilteredElementCollector collector = new FilteredElementCollector(doc);collector = collector.OfClass(typeof(FamilySymbol);var query = from element in collector where element.Name =测斜管 /查找名为“测斜管”的族实例 select element; /linq 查询List famSyms = query.ToList();ElementId symbolId = famSyms0.Id;/创建过滤器并找到该族类型对应的所有族实例collector = new FilteredElementCollector(doc);FamilyInstanceFilter filter = new FamilyInstanceFilter(doc, symbolId);IList founds = collector.WherePasses(filter).ToElements();foreach(FamilyInstance inst in founds)TaskDialog.Show(Revit, string.Format(FamilyInstance:t0nFamilySybmol Id:t1nName:t2, inst.Id.IntegerValue,inst.Symbol.Id.IntegerValue,inst.Symbol.Name);/新建对话框，选择是否删除查找到的族实例TaskDialog mainDialog = new TaskDialog(删除);mainDialog.MainContent = 单击Ok删除传感器！;mainDialog.CommonButtons = TaskDialogCommonButtons.Ok | TaskDialogCommonButtons.Cancel;if (TaskDialogResult.Ok = mainDialog.Show()/对元件进行编辑都必须新建事件来解决using (Transaction delTrans = new Transaction(doc, delete the element!) delTrans.Start(); doc.Delete(founds0.Id); delTrans.Commit(); 3.2 通过族名查找族类型/用到了快过滤器：FamilySymbolFilterUIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;FilteredElementCollector collector = new FilteredElementCollector(doc);collector = collector.OfClass(typeof(Family);var query = from element in collector where element.Name = 测斜管 select element; /Linq查询List fam= query.ToList();ElementId famId = fam0.Id;/创建过滤器并找到该族对应的所有族类型collector = new FilteredElementCollector(doc);FamilySymbolFilter filter = new FamilySymbolFilter(famId);/收集族类型名称IList founds = collector.WherePasses(filter).ToElements();foreach (FamilySymbol syms in founds)TaskDialog.Show(Revit, string.Format(FamilySymbol:t0nFamily Id:t1nName:t2,syms.Id.IntegerValue, syms.Family.Id.IntegerValue, syms.Family.Name);/收集族类型IDICollection found= collector.WherePasses(filter).ToElementIds();foreach (ElementId symsId in found)TaskDialog.Show(Revit, string.Format(FamilySymbol Id:t0nName:t1, symsId.IntegerValue, symsId.ToString();4.实例的隔离与颜色改变4.1 实例的颜色改变UIDocument uidoc = commandData.Application.ActiveUIDocument;Document doc = uidoc.Document;/过滤填充图案FilteredElementCollector fillPatternFilter = new FilteredElementCollector(doc);fillPatternFilter.OfClass(typeof(FillPatternElement);/获取实体填充FillPatternElement fp = fillPatternFilter.First(m = (m as FillPatternElement).GetFillPattern().IsSolidFill) as FillPatternElement;Reference hasPickOne = uidoc.Selection.PickObject(ObjectType.Element);if (hasPickOne != null)Transaction trans = new Transaction(doc, trans); trans.Start();View v = doc.ActiveView;OverrideGraphicSettings ogs = v.GetElementOverrides(hasPickOne.ElementId);Color oldColor = ogs.ProjectionFillColor; /实例的现在颜色ElementId oldEleId = ogs.ProjectionFillPatternId; /现在的fillPatternid/设置 投影/表面 -填充图案-填充图案ogs.SetProjectionFillPatternId(fp.Id);/设置 投影/表面 -填充图案-颜色ogs.SetProjectionFillColor(new Color(255, 0, 0);/应用到视图v.SetElementOverrides(hasPickOne.ElementId, ogs);trans.Commit();return Result.Succeeded;4.2 实例的隔离与恢复显示 单独构建：1. varui=commandData.Application.ActiveUIDocument;2. vardoc=ui.Document;3. 4. varselect=ui.Selection;5. varrefe=select.PickObject(ObjectType.Element);6. 7. using(Transactiontrans=newTransaction(doc)8. 9. trans.Start(isloate);10. ui.ActiveView.IsolateElementTemporary(refe.ElementId);11. trans.Commit();12. 构建组：1. varui=commandData.Application.ActiveUIDocument;2. vardoc=ui.Document;3. varselect=ui.Selection;4. v
