I have no idea how to go about opening all selected families, changing the “Room Calculation Point” parameter to “True” then loading it back into a project and Overwrite the existing version and its parameter values.

just guessing here but, if you are interested in getting the room an element is in check this: [image] Collect roomnumber and push roomnumber in each element inside the room, but somehow I have a missing link Revit Hello, I would fill the parameter Comments with the room …

Sorry this isn’t what I’m looking, thanks anyway.

Orchid package has a bunch of good family editing nodes, or there are plenty of good python examples on here. It does also appear the room calc point param is exposed based on this post. https://forums.autodesk.com/t5/revit-api-forum/room-calculation-point-parameter/td-p/3924857

I would first save out the family library (basic Revit, no Dynamo involved) to a new folder.

Hi guys, Regarding this post. I have tried to find a way to set a bunch of Familys with “Room calculation Point” on. I can understand that I need to open and close every family document. there must be a way to set this easy with Dynamo? Anders

Hi Anders Have you got this working? I am trying to run this script on a 2018 model it does not give any errors but does not acvtivate the room calculation point. Thanks

Same here. I have to run it once to make the room calc point parameter selectable, I select it, rn again and it runs with no errors but none of my families room calc points are turned on.

Is it possible to change the Room Calculation Point for all families in a project?
