Hi, I am looking to add a parameter to a family that will pick up a parameter in a linked architectural model. We have modelled MEP builderswork openings within various walls and I want to schedule out the fire and acoustic rating against each opening. The fire and acoustic rating are under a parameter within a linked model. I just don't know how to work out which wall each opening sits within. I have been using filters etc... to manually input this data however looking to see if anyone has done anything similar to make the process more automatic? Hope this makes sense, any suggestions would be appreciated. Thanks, Scott
