Do you have some clue ?

HI @Anonymous,

Are you trying to get the room , where your element is present?

If that's the case try the below code.

Element e;      
FamilyInstance Fi = e as FamilyInstance;                      
String  s =Fi.ToRoom.Name;

Hi @naveen.kumar.t

Thanks for reply !

I just tested your code like these :

try
 {

 FamilyInstance fi = e as FamilyInstance;
 if (fi != null && fi.Room != null)
 {
 string s = fi.Room.Name;
 }
 } catch (Exception eaze)
 {
 var x = 1;
 }

But it seem like "FI.ROOM" is always null... but i'm sure that i have 4 room in my project 😕

Hi,

if your element is not a FamilyInstance (and does not have ToRoom, Room, FromRoom properties), you may use

Document.GetRoomAtPoint:

Hi @Revitalizer,

Thanks for reply !

I followed your link and i still can't get the room..

Here how i get my elements and then how i process to get the room

 FilteredElementCollector collector = new FilteredElementCollector(m_doc); 
 IList<Element> m_elementsToProcess = collector.WhereElementIsNotElementType().ToElements();

//
//
//

LocationPoint lp = e.Location as LocationPoint;
 if (lp != null)
 {
   XYZ myloc = lp.Point;
   if (myloc != null)
   {
     Room myRoom = m_doc.GetRoomAtPoint(myloc);
     if (myRoom != null)
     {
       string s = myRoom.Name;
     }
   }  
 }

But "myRoom" is always null..

Any idea ?

Hi,

two remarks:

GetRoomAtPoint gets the room from the final Phase, so, you may use its GetRoomAtPoint(XYZ, Phase) overload to test each Phase.

Location may be slightly out of the room's volume, so make sure the point you are testing is inside the room volume and not just under it, e.g. by adding some amount to its Z value.

Hi,

For phase it's okay, we aren't using them at the moment.

Thanks for the type of the Z.

By the way, I have somes door who aren't considering in any room, so i was looking to adjust the X or Y point, but it's readonly, same for the 'Z' and i didn't find method to set it, what should I use ?

I used this 

XYZ myloc = lp.Point;
 if (myloc != null)
 {
 XYZ vector = new XYZ(0, 0, 1);
 vector.Add(myloc);
 Room myRoom = m_doc.GetRoomAtPoint(vector);

Gonna make some test 🙂

Hi,

you cannot change an existing XYZ but create a new one, for using as input in the GetRoomAtPoint method.

XYZ testPoint = new XYZ(yourPoint.X, yourPoint.Y, yourPoint.Z+0.5); // add the half of a foot to Z value

Hi,

for the FromRoom/ToRoom properties, they depend on how the Families are defined (existing RoomCalculationPoint or not), plus the user can switch the logical (not the geometrical) direction via a door schedule view.
