Set parameter Value of a window family

Hi all,

I am trying to set the ’ Width ’ parameter of my Window Family to 800mm.( it is now 400mm ).
However the Set.ParameterByName node gives me the following error:

’ The parameters storage type is not a string ’ .

What does this error mean?

Thanks in advance!


set width of window family|690x297

set width of window family

A String is a text, this parameter will only take numeric values.
use a code block and type 800 in it, that will give you the number 800, 200+600 in the code block will also give you 800, “200”+“600” in the code block will give you 200600 (text)
