revit api视图

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
}

获取视图中可见元素

//找到视图中所有可见的元素
FilteredElementCollector elemCollector = new FilteredElementCollector(document, viewId);
foreach (Element elem in elemCollector)
{//操作元素elem
}//============代码片段8-3：创建一个正交三维视图============
private void CreateView3D(Autodesk.Revit.Document doc, ElementId viewTypeId)
{try{// Create a new View3DXYZ direction = new XYZ(1, 1, 1);View3D view3D = View3D.CreateIsometric(doc, viewTypeId);if (null == view3D)return;// The created View3D isn't perspective.Debug.Assert(false == view3D.IsPerspective);}catch (Exception e){Debug.WriteLine(e.ToString());}
}

显示剖面框

private void ShowHideSectionBox(View3D view3D)
{view3D.IsSectionBoxActive = true;
}

 创建和打印一个图纸视图

private void CreateSheetView(Autodesk.Revit.Document doc)
{// Get an available title block from documentFamilySymbolSet fsSet = doc.TitleBlocks;if (fsSet.Size == 0){MessageBox.Show("No title blocks");return;}FamilySymbol fs = null;foreach (FamilySymbol f in fsSet){if (null != f){fs = f;break;}}try{// Create a sheet viewViewSheet viewSheet = ViewSheet.Create(doc, fs);if (null == viewSheet)return;// Add current view onto the center of the sheetUV location = new UV((viewSheet.Outline.Max.U - viewSheet.Outline.Min.U) / 2,(viewSheet.Outline.Max.V - viewSheet.Outline.Min.V) / 2);XYZ point = new XYZ(UV.U, UV.V, 0);Viewport.Create(doc, viewSheep.Id, doc.ActiveView.Id, point);// Print the sheet outif (viewSheet.CanBePrinted){if (MessageBox.Show("Print the sheet?", "Revit",
MessageBoxButtons.YesNo) == DialogResult.Yes)viewSheet.Print();}}catch (Exception e){MessageBox.Show(e.ToString());}
