That is because the Get Parameter nodes works in the context of the current doc, not the linked doc. If you want to get that info you may need to use a package like Beaker or Orchid to get it from the linked doc.
No problem, if I find time this week to do some tests (the node is already developed), I’ll get it published and update this thread so you know when its available on the package manager - glad to hear BimorphNodes is proving useful.
It is indeed. Overall I have to copy monitor a bunch of walls and need them to be the same type. May not be the best way but I am getting all of the walls from both models and checking to see if a linked wall is in the BBox of the host models wall. I know this is very processor heavy but BoundingBox.GetElementsInside chews it right up. Thanks for all of your help.
