视图

视图是从Revit模型产生的图像，其对文件中存储的数据有特许访问权。它们可以是图形，如平面图;或文本，如明细表。每个项目文件都有一个或多个不同视图。最后一个焦点窗口是活动视图ActiveView。每个视图的生成都是从三维对象投影到二维投影面的过程。
Autodesk. Revit.DB. View类是Revit文件中所有视图类型的基类。Autodesk. Revit.Ul.UIView类表示在Revit用户界面中的窗口视图。

//获得当前视图id
ElementId viewId = uidoc.ActiveView.Id;

视图类型

Autodesk.Revit.DB.View类是Revit文件中所有视图类型的基类；Autodesk.Revit.UI.UIView类表示在Revit用户界面中的窗口视图。

常见视图类型

视图	视图类型	视图类
三维视图	ViewType.ThreeD	View3D
天花板平面视图	ViewType.CeilingPlan	ViewPlan
面积平面视图	ViewType.AreaPlan	ViewPlan
剖面视图	ViewType.Section	ViewSection
图纸视图	ViewType.DrawingSheet	ViewSheet
明细表视图	ViewType.Schedule	ViewSchedule

//获取视图类型
//Autodesk.Revit.DB.View view = GetView();
//两种判断视图类型的方法：
//第一种：
ViewType viewType = view.ViewType;
switch (viewType)
{case Autodesk.Revit.DB.ViewType.ThreeD:// 视图类型是三维视图break;// 其他类型
}// 第二种：
if (view is View3D)
{// view的类类型是三维视图
}

public void GetViewType(Autodesk.Revit.DB.View view)
{// Get the view type of the given view, and format the prompt stringString prompt = "The view is ";switch (view.ViewType){case ViewType.AreaPlan:prompt += "an area view.";break;case ViewType.CeilingPlan:prompt += "a reflected ceiling plan view.";break;case ViewType.ColumnSchedule:prompt += "a column schedule view.";break;case ViewType.CostReport:prompt += "a cost report view.";break;case ViewType.Detail:prompt += "a detail view.";break;case ViewType.DraftingView:prompt += "a drafting view.";break;case ViewType.DrawingSheet:prompt += "a drawing sheet view.";break;case ViewType.Elevation:prompt += "an elevation view.";break;case ViewType.EngineeringPlan:prompt += "an engineering view.";break;case ViewType.FloorPlan:prompt += "afloor plan view.";break;case ViewType.Internal:prompt += "Revit's internal view.";break;case ViewType.Legend:prompt += "a legend view.";break;case ViewType.LoadsReport:prompt += "a loads report view.";break;case ViewType.PanelSchedule:prompt += "a panel schedule view.";break;case ViewType.PresureLossReport:prompt += "a pressure loss report view.";break;case ViewType.Rendering:prompt += "a rendering view.";break;case ViewType.Report:prompt += "a report view.";break;case ViewType.Schedule:prompt += "a schedule view.";break;case ViewType.Section:prompt += "a cross section view.";break;case ViewType.ThreeD:prompt += "a 3-D view.";break;case ViewType.Undefined:prompt += "an undefined/unspecified view.";break;case ViewType.Walkthrough:prompt += "a walkthrough view.";break;default:break;}// Give the user some informationTaskDialog.Show("Revit",prompt);
}

视图的方法

新建视图

每个视图类都有相应的函数来创建视图对象

例如：

public static ViewPlan Create(Document document, ElementId viewFamilyTypeId, ElementId levelId);
public static ViewPlan CreateAreaPlan(Document document, ElementId areaSchemeId, ElementId levelId);

参数	类型	说明
document	Type: Autodesk.Revit.DB.Document	ViewPlan将被添加到其中的文档。
viewFamilyTypeId	Type: Autodesk.Revit.DB.ElementId	ViewFamilyType的id，它将被新的ViewPlan使用。类型需要是楼板平面FloorPlan, 天花板平面CeilingPlan,面积平面 AreaPlan，或结构平面StructuralPlan视图类型。
levelId	Type: Autodesk.Revit.DB.ElementId	与新视图关联的标高id。

public Autodesk.Revit.UI.Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements){try{Document doc = commandData.Application.ActiveUIDocument.Document;Transaction tran = new Transaction(doc);tran.Start("创建标高");CreateViewPlane(doc, GetAllLevels(doc).Last()).Name = "新建楼层平面";tran.Commit();return Autodesk.Revit.UI.Result.Succeeded;}catch (Exception ex){message = ex.Message;return Autodesk.Revit.UI.Result.Failed;}}private ViewPlan CreateViewPlane(Document doc, Level level){List<ViewPlan> allFloorPlanes = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Views).OfClass(typeof(ViewPlan)).WhereElementIsNotElementType().OfType<ViewPlan>().ToList();foreach (ViewPlan view in allFloorPlanes){if (view.ViewType == ViewType.FloorPlan && view.GenLevel != null && view.GenLevel.Id == level.Id){doc.Delete(view.Id);break;}}doc.Regenerate();return ViewPlan.Create(doc, doc.GetDefaultElementTypeId(ElementTypeGroup.ViewTypeFloorPlan), level.Id);}private IList<Level> GetAllLevels(Document doc){return new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Levels).OfClass(typeof(Level)).ToElements().OfType<Level>().ToList();}

要删除一个视图可以使用Document. Delete方法,传入一个视图的ID，doc.Delete(view.Id);。也可以通过删除该视图所依赖的对象来间接删除该视图,例如,删除标高,相应的平面视图也会被删除,或者删除相机,相应的三维视图也会被删除。
