Not my script btw
I think what’s happening is it’s moving walls… Dynamo obviously does nodes in sequence not parallel and some are done AFTER the wall moves. Hence a different figure.
That’s my guess anyway.
“Base Offset” is an odd name for a user to name a parameter, specifically for walls as they’d already have such. Not saying it couldn’t happen, but it’s not one of the common duplicates I see (I used to see a “why do I have 32 ‘color’ parameters” case once a week when I took cases)
