更多Revit API 里有個(gè)BuildingEnvelopeAnalyzer類(lèi)，幫助文檔里對(duì)它描述如下：
This class uses a combination of ray-casting and flood-fill algorithms in order to find the building elements that are exposed to the outside of the building. This method can also look for the bounding building elements for enclosed space volumes inside the building.
大概意思就是說(shuō)這個(gè)類(lèi)可以獲取在建筑外面的建筑構(gòu)件，
下面是一個(gè)小測(cè)試，
Document doc = commandData.Application.ActiveUIDocument.Document;
BuildingEnvelopeAnalyzerOptions opt = new BuildingEnvelopeAnalyzerOptions();
opt.AnalyzeEnclosedSpaceVolumes = true;
opt.OptimizeGridCellSize = false;
opt.GridCellSize = 1;
BuildingEnvelopeAnalyzer analyzer = BuildingEnvelopeAnalyzer.Create(doc, opt);
IList<LinkElementId> ids = analyzer.GetBoundingElements();
List<ElementId> nids = ids.Select(m => m.HostElementId).ToList();
UIDocument uidoc = new UIDocument(doc);
uidoc.Selection.SetElementIds(nids);
return Result.Succeeded;
