How to Obtain the System Family?

[Anonymous]

Hi everyone, I want to retrieve the Family of the System Elements (such as for example the "Basic Wall" for a wall), but not only the family name. I want at less the ID of this family. It is posible?

I know that from Symbols families is posible to obtain it. but i think a Wall doesn't have a FamilySymbol.

Dear Mustafa.Salaheldin,

thanks for your answer but:

By this way I obtain the Type of the element, but i continue without obtain the Family, only can obtain the family Name (in your code: item.FamilyName). For example for the ElementType Generic - 8", i want the wall Family to which it belongs.

Actually, only can obtain the Name of this family. It is possible to obtain the Family object or, at least, the Id of it?

Thanks

Hi,

Walls are not Family based, thus no Family to get.

They reference a WallType, that is the equivalent to a FamilySymbol.

If there is a project Family, an in-place Family of category "Walls", this is a special kind of "Wall" since it is a FamilyInstance without a WallType assigned, but with FamilySymbol and Family.
