Revit - 将分割表面应用于墙壁

Question

我编写了一个程序，该程序使用对形状面的引用来形成分割面。但是当应用于墙壁时（带有类别选择的搜索字符串在下面突出显示），该程序什么也不做。如何仅将此程序应用于项目中的所有墙壁？

   public class Command : IExternalCommand
    {
        public Result Execute(
          ExternalCommandData commandData,
          ref string message,
          ElementSet elements)
        {
            UIApplication app = commandData.Application;
            Document doc = app.ActiveUIDocument.Document;

            Autodesk.Revit.Creation.Application creApp
              = app.Application.Create;

            try
            {
                FilteredElementCollector forms = new FilteredElementCollector(doc);
                forms.OfCategory(BuiltInCategory.OST_CurtainGridsWall); // !!problem string!!

                using (Transaction tx = new Transaction(doc))
                {
                    tx.Start("Create Devided Surface");

                    foreach (Form form in forms)
                    {
                        FamilyItemFactory factory = doc.FamilyCreate;
                        Options options = creApp.NewGeometryOptions();
                        options.ComputeReferences = true;
                        options.View = doc.ActiveView;
                        GeometryElement element = form.get_Geometry(options);

                        foreach (GeometryObject geoObject in element) // 2013
                        {
                            Solid solid = geoObject as Solid;
                            foreach (Face face in solid.Faces)
                            {
                                if (face.Reference != null)
                                {
                                    if (null != face)
                                    {

                                    }
                                }
                            }
                        }
                    }
                    tx.Commit();
                }

                return Result.Succeeded;
            }
            catch (Exception ex)
            {
                message = ex.Message;
                return Result.Failed;
            }
        }
    }

如果你需要找到当前文档中的所有墙，只需将BuiltInCategory.OST_CurtainGridsWall更改为BuiltInCategory.OST_Walls，并将元素转换为Autodesk.Revit.DB.Wall，如下所示：

UIApplication app = commandData.Application;
Document doc = app.ActiveUIDocument.Document;
var walls = new FilteredElementCollector(doc)
    .OfCategory(BuiltInCategory.OST_Walls)
    .WhereElementIsNotElementType()
    .Cast<Autodesk.Revit.DB.Wall>
    .ToList();

如果您需要项目中所有文件的墙您需要先获取所有链接文档（链接文档应加载到项目中，否则找不到它们），如下所示：

UIApplication app = commandData.Application;
var doc = app.ActiveUIDocument.Document;
List<Autodesk.Revit.DB.Document> linkedDocs = new Autodesk.Revit.DB.FilteredElementCollector(doc)
                .OfClass(typeof(Autodesk.Revit.DB.RevitLinkInstance))
                .Cast<Autodesk.Revit.DB.RevitLinkInstance>()
                .Select(x => x.GetLinkDocument())
                .ToList();

然后，对于每个文档，重复接收墙。
