[Revit二次开发] 使用轮廓生成房间

使用RevitAPI创建房间的时候有挺多地方不是特别明确的，对于我原本就很少，几乎没有在Revit中手动操作过房间的人来说就更难理解了。

RevitAPI Demo

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;
}

使用API创建房间的方法有三个：

public Room NewRoom(Phase phase)

public Room NewRoom(Level level,UV point)

public Room NewRoom(Room room,PlanCircuit circuit)

假如你已经有了一个闭合的轮廓需要在轮廓内创建房间的话，可以使用以下方法：

• 绘制房间分隔

  //创建房间分隔
  CurveArray slabCurveArray = new CurveArray();
  foreach (var vmCeilingEdgeInfo in vm.CeilingEdgeInfos)
  {
  slabCurveArray.Append(vmCeilingEdgeInfo.Edge);
  }

  var sketchPlane = SketchPlane.Create(ActiveDocument, Plane.CreateByNormalAndOrigin(-bottomFace.FaceNormal, bottomFace.Origin));

  var viewPlan = FilterUtils.FilterByFunc(ActiveDocument, o => o.LookupParameter(“相关标高”)?.AsString() == level.Name).FirstOrDefault();

  roomSepartions = ActiveDocument.Create.NewRoomBoundaryLines(sketchPlane, slabCurveArray, viewPlan);

  ActiveDocument.Regenerate();

• 获取项目中同标高的所有轮廓并判断该轮廓是否已经生成房间

  PlanCircuit planCircuit = null;
  PlanTopology planTopology = ActiveDocument.get_PlanTopology(level);
  foreach (PlanCircuit circuit in planTopology.Circuits)
  {
  if (null != circuit && !circuit.IsRoomLocated)
  {
  planCircuit = circuit;
  break;
  }
  }

• 创建房间（此方法中的阶段phase参数假如你不需要可以为null）

  //创建房间
  if (null != planCircuit)
  {
  var room = ActiveDocument.Create.NewRoom(null, planCircuit);
  }

PS：

• 创建完房间后不可删除房间分隔线，否则房间则会变成没有轮廓范围而且没有面积的房间
• 创建房间的视图必须是平面视图，如果不是平时图则会报错（“尝试读取或写入受保护的内存。这通常指示其他内存已损坏”）。
