Autodesk Revit MEP 2010 .NET API C# 房间到门的关系

发布于 2024-08-07 06:57:24 字数 1192 浏览 5 评论 0原文

在 C# 中使用 VS 2008 和 Autodesk Revit MEP 2010 我试图查明门是否连接到房间：

ElementSetIterator elementsetiteratorBIMDoors = 
  bimdoors.getBIMDoors().ForwardIterator();

while (elementsetiteratorBIMDoors.MoveNext())
{
    Autodesk.Revit.Element elementDoor = 
      elementsetiteratorBIMDoors.Current as Autodesk.Revit.Element;

    if ((null != elementDoor.get_Parameter(BuiltInParameter.FROM_ROOM_ID)) && 
        (null != elementDoor.get_Parameter(BuiltInParameter.TO_ROOM_ID)))
    {
        string sDoorFromRoomID = 
              elementDoor.get_Parameter(BuiltInParameter.FROM_ROOM_ID).ToString();
        string sDoorToRoomID = 
              elementDoor.get_Parameter(BuiltInParameter.TO_ROOM_ID).ToString();

        graph.addLink(new Link(sDoorFromRoomID, sDoorToRoomID));
    }
}

此方法不起作用，因为 elementDoor.get_Parameter(BuiltInParameter.FROM_ROOM_ID) 的返回值始终为null。

我在 Building Coder 博客上读到

内置参数不是 API 的官方支持部分。在未来我们预计它将被正确公开的数据所取代属性。

这种说法属实吗？谁能指出一种有效的方法来获取门和房间之间的关系？

Working with VS 2008 and Autodesk Revit MEP 2010 in C# I am trying to find out if a door is connecting to rooms:

ElementSetIterator elementsetiteratorBIMDoors = 
  bimdoors.getBIMDoors().ForwardIterator();

while (elementsetiteratorBIMDoors.MoveNext())
{
    Autodesk.Revit.Element elementDoor = 
      elementsetiteratorBIMDoors.Current as Autodesk.Revit.Element;

    if ((null != elementDoor.get_Parameter(BuiltInParameter.FROM_ROOM_ID)) && 
        (null != elementDoor.get_Parameter(BuiltInParameter.TO_ROOM_ID)))
    {
        string sDoorFromRoomID = 
              elementDoor.get_Parameter(BuiltInParameter.FROM_ROOM_ID).ToString();
        string sDoorToRoomID = 
              elementDoor.get_Parameter(BuiltInParameter.TO_ROOM_ID).ToString();

        graph.addLink(new Link(sDoorFromRoomID, sDoorToRoomID));
    }
}

This approach does not work because the return value of elementDoor.get_Parameter(BuiltInParameter.FROM_ROOM_ID) is always null.

I have read on the Building Coder blog that

Built-in parameters are not an officially supported portion of API. In
future we expect it will be replaced by data being properly exposed as
a property.

Is that statement true? Can anyone point me to an efficient way to get the relation between doors and rooms?

门是家庭实例，因此

Autodesk.Revit.Elements.FamilyInstance elementDoor = elementsetiteratorBIMDoors.Current as Autodesk.Revit.Elements.FamilyInstance;

Room fromRoom = elementDoor.FromRoom;
Room toRoom = elementDoor.ToRoom;

应该适用于此。

Doors are family instances, so

Autodesk.Revit.Elements.FamilyInstance elementDoor = elementsetiteratorBIMDoors.Current as Autodesk.Revit.Elements.FamilyInstance;

Room fromRoom = elementDoor.FromRoom;
Room toRoom = elementDoor.ToRoom;

should work for this.
