Create Multiple Elevation Views From Filtered Wall Types In A Linked Revit Model

I want to create exterior building elevation views in my Revit model based on walls of a certain type in a linked Revit model, then place those views on sheets. Is there a way to do this?

I tried filtering the walls but got stuck at the “get location from element id” since element ID’s can’t be pulled from a linked model.

I would also like to avoid copying & pasting the walls, but if it’s unavoidable, I understand.

Hello Mel!!

You can always try and get the Geometry off of the element then from that geometry get the location on the project if thats what you want, just remember that location for walls in revit returns as a Line which determines the length of the wall. Ive always found elevations to be a little tricky, worked on a similar project a few months ago an decided to work with sections rather than elevations.

Hi @mbolinSTBLH and Welcome, yes its possible even on linked elements, but not with OOTB gues its only support sections…for create viewports we have ootb for that…
