Revit floor span direction

Hi there.
Has anybody had succes or an idea of how to get the span direction from Revit structural floors in Grasshopper?
Thanks in advance.

Best regards Rasmus

one way would be over Span Direction parameter and then using the angle to get direction vector

Perfect - I didn’t think of this way of extracting the parameters.
Could’nt get it by text input - clearly the parameter key is a different type.
