Hi.

I was trying to append the room name variable from the architecture attachment to revit and assign the parameter value to the Space variable in the MEP model, however I encountered a problem, Dynamo broke and exited afterward, sometimes the file only run in less than a minute, someone please give me any reasons or solutions, thanks!
Node main :

And Next, Dynamo Crash And Revit Exit

I have attached the dyn file I created below.

Set Space MEP Follow Room _01.dyn (99.6 KB)

Do all of your elements have valid bounding boxes, ie, are any of them null or have 0 dimensions? Also providing only the graph is useless without the model!
