Revit二次開發-根據視圖階段(Phase)創建房間

最近開發業務中,有一個自動創建房間的功能,很自然的想到了Document.NewRooms2方法。但是當前功能的特殊之處在於,Revit項目視圖是分階段(Phase)的,不同階段的房間是互相獨立的。
官方API中創建房間提供了三個重載方法:
1 public ICollection<DB.ElementId> NewRooms2(Phase phase, int count); 2 public ICollection<DB.ElementId> NewRooms2(Level level); 3 publicICollection<DB.ElementId> NewRooms2(Level level, Phase phase)
第二個以前經常用,所以自然先用這個方法創建房間。但是結果不遂人意,因為項目視圖是分階段的,所以用這個方法在創建房間時,在有些視圖是失敗的,功能不穩定,所以這個方法不適用。
第一個方法是帶有Phase參數的,但是個數又不確定,顯然不滿足需要。
第三個方法彌補第一個方法的不足,看上去應該滿足需要,但是結果跟第一個差不多,在有些視圖階段是創建不出來房間的,會提示 階段和當前視圖不匹配的錯誤。這個就讓人很困惑了。
沒辦法,只能求助百度了,剛好找到了網友的一片文章 https://blog.csdn.net/u010585773/article/details/83267904 其中介紹創建房間的方法,這篇博客講了通過閉合區間創建房間,讓做了好幾年Revit開發的我找到了新大陸,原來Revit竟然提供了這個方法,一直沒有研究過。於是系統的研究總結一下,提供下面兩種創建方式:
第一種是在當前業務中使用:
private List<Room> CreateRooms() { List<Room> roomList = new List<Room>(); List<Level> levelList = wrapper.Doc.GetLevels().OrderBy(p => p.Elevation).ToList(); Level level = levelList[0]; List<Phase> phaseList = wrapper.Doc.GetElements<Phase>(); ListView Code<ElementId> roomIdList = new List<ElementId>(); Phase viewPhase = wrapper.ActiveView.GetParameterElement(BuiltInParameter.VIEW_PHASE) as Phase; double minRoomArea = (2.0).ConvertToAPI(DisplayUnitType.DUT_SQUARE_METERS); Transaction trans = new Transaction(wrapper.Doc, "CreateRoom"); trans.Start(); try { PlanTopology planTopology = wrapper.Doc.get_PlanTopology(wrapper.ActiveView.GenLevel, viewPhase); if (planTopology != null) { var arry = planTopology.Circuits; foreach (PlanCircuit item in arry) { if (!item.IsRoomLocated && item.Area > minRoomArea) { Room room = wrapper.DocCreater.NewRoom(null, item); roomList.Add(room); } } } trans.Commit(); } catch (Exception ex) { trans.RollBack(); } return roomList; }
第二種是RevitAPI中官方示例:
Room InsertNewRoomInPlanCircuit(Autodesk.Revit.DB.Document document, Level level, Phase newConstructionPhase) { // create room using Phase Room newScheduleRoom = document.Create.NewRoom(newConstructionPhase); // set the Room Number and Name string newRoomNumber = "101"; string newRoomName = "Class Room 1"; newScheduleRoom.Name = newRoomName; newScheduleRoom.Number = newRoomNumber; // Get a PlanCircuit PlanCircuit planCircuit = null; // first get the plan topology for given level PlanTopology planTopology = document.get_PlanTopology(level); // Iterate circuits in this plan topology foreach (PlanCircuit circuit in planTopology.Circuits) { // get the first circuit we find if (null != circuit) { planCircuit = circuit; break; } } Room newRoom2 = null; if (null != planCircuit) { using (Transaction transaction = new Transaction(document, "Create Room")) { if (transaction.Start() == TransactionStatus.Started) { // The input room must exist only in the room schedule, // meaning that it does not display in any plan view. newRoom2 = document.Create.NewRoom(newScheduleRoom, planCircuit); // a model room with the same name and number is created in the // view where the PlanCircuit is located if (null != newRoom2) { // Give the user some information TaskDialog.Show("Revit", "Room placed in Plan Circuit successfully."); } transaction.Commit(); } } } return newRoom2; }View Code
