Change yes/no instance parameter of objects using their elements id


Hello again,

I’m am trying to change the yes/no instance parameter called “Visible” in several objects in my revit model. I have an excel file containing a list element id numbers
of objects I wish to change.

Studying examples I thought I got it. I have the beginning and the end. I need help in the middle. Hopefully it’s an easy one…

Thanks in advance.


For doc there should be a node called current document in archi-lab and the Ids should take the number.


Hi Paul,

You need to connect “Current Document” from Archi-lab package to “Doc” in your “Id to Element”. See below example. Good Luck!


John…Thank you.


Do you mind checking my graph. It’s exactly like yours but gets a null in “Id to Element”.

Test Yes-No


Flatten your list and use string to number to convert the data.



I think this is what you meant? What am I doing wrong?
