@scottd I’ve managed to replicate this and I just wanted to confirm something.
Your method is getting all of the geometry from a linked model based on the LINKED MODEL’S view, correct? So for this to work, each model would need to have the view setup and filters applied within that model.
What I was after was using the active’s model view settings (inc filters and hidden elements) to return the linked geometry. Does this make sense? It sounds like it might not be possible.
