Rooms Parameters

[Anonymous]

Hi,

I'm trying to get all rooms' parameters in a file without any room.

I tried the following code but I notice that I can get all families but rooms and areas:

FilteredElementCollector elementCol = new FilteredElementCollector(doc).OfClass(typeof(FamilySymbol));

also

FilteredElementCollector elementCol = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Rooms);

this only works if I have at least one room in the file.

Anyone can help me?

The easiest solution is to start a transaction, create a dummy room element, retrieve and save its parameters, and roll back the transaction without committing it. This is also know as the temporary transaction trick TTT. Here are many other examples of using it:
