Get room informations from FamilySymbol

[Anonymous]

Hello,

how can i get the room informations from a FamilySymbol? With a FamilyInstance it works, but not with FamilySymbol:

Thanks

It is because a FamilySymbol does not exist in a room. It is the top level element for a Family that holds the Types, but the FamilyInstance is what is placed in the model and therefore can have room information.

I have the following problem. In instance object I get all the parameters without values. In the symbol object I only get the parameters assigned to the family with the values but not the room. How do i get the room information and the assigned parameters with values?

Perhaps I am a bit confused, but I understood that you were trying to get information from the Room, and supply it to your Family inside that room. If that is true, you would be using Instance Based parameters which would not require the Family Symbol. If you are trying to set Type Parameters, then you need to get the Family Type.  

ElementType fType = doc.GetElement(famInst.GetTypeId) as ElementType;

If this is not what you are trying to do, could you please explain a little more on what you expect the result to be?

Thanks, this is the solution what i need. The last point to finish my function is, how can i select only a FamilyInstance, perhaps with a if statement? Like: if (SpecialityEquipmentElementsMain[iEquipment] == "FamilyInstance") ....

I think you should be able to use the "is" statement to get this done.

Example:

        private Room FamRoom()
        {
            IList<FamilyInstance> fams = new FilteredElementCollector(doc).OfClass(typeof(FamilyInstance)).Cast<FamilyInstance>().ToList();
            if (fams[12] is FamilyInstance famIst)
            {
                Room room = famIst.Room;
                return room;
            }
            return null;
        }
