I have run in the same situation. Only some of the sheets need North arrow, I only turn on the North arrow on plans not on the elevation, sections and other details sheets.
Joe,
I’ve got the same problem, did you ever find a solution to this?
I want to turn off all north arrows on my sheets that contain views with the word ‘plan’ in them.
I’ve been able to select all sheets in the project and filter the instance parameter to be a boolean value (true=north arrow on, false=north arrow off)
But if you got any further in developing a way to do it that’d be great,
Cheers
