c# - 如何使用 Revit API 激活（显示）视图（平面图或标高）？

Question

我正在尝试使用 Revit API 激活视图。我想要做的是显示水平或平面图视图。所以我要激活的视图（我的意思是，我希望这个视图实际显示在屏幕上）已经存在，我可以访问它的 ID。

我已经看到有关创建、浏览、过滤视图的线程，但没有激活它……这是一个平面图视图。（我想要的是通过选择一个级别/平面图，它会在屏幕上显示该级别/平面图（就像从现有的 Revit 模型中打开该平面图以显示在用户屏幕上一样）。

Answer 1

这是一个如何切换到默认 3d 视图的示例 https://thebuildingcoder.typepad.com/blog/2011/09/activate-a-3d-view.html

您可以对所有其他可用视图执行相同的操作

    UIApplication uiapp = commandData.Application;
    UIDocument uidoc = uiapp.ActiveUIDocument;
  
    uidoc.ActiveView = yourview;

从一个级别创建一个视图，您的代码看起来像这样

ViewFamilyType viewFamilyType = (from elem in new 
    FilteredElementCollector(doc)
    .OfClass(typeof(ViewFamilyType))
    let type = elem as ViewFamilyType
    where type.ViewFamily == ViewFamily.FloorPlan
    select type).FirstOrDefault();

using (Transaction t = new Transaction(doc))
{
    t.Start("Create View");
    var floorPlan = ViewPlan.Create(doc, viewFamilyType.Id, yourLevel.Id);
    floorPlan.Name = "NewView";
    t.Commit();
}

Answer 2

FilteredElementCollector viewCollector = new FilteredElementCollector(doc);

                viewCollector.OfClass(typeof(View));

                foreach (Element viewElement in viewCollector)
                {
                        yourview = (View)viewElement;
                      
                        break;  
                }
            }

            uidoc.ActiveView = yourview;

Answer 3

超级容易做到：

# normally you have the ui set at the start of your script
ui = __revit__.ActiveUIDocument 

# then just set the ActiveView as your view (not the ViewId)
ui.ActiveView = yourView
