If they are being imported in an IFC file, wouldn't those elements need to be set correctly in whatever software is creating the IFC file?
I'm only talking about the graphic attributes like pens and line types, and also more importantly story visibility settings.
For example, the default setting for Floor Plan Display is "All Relevant Stories", but we would prefer it to be "Home Story Only".
We're trying to do things like have our Mechanical consultant's ducts show on our RCPs when there is exposed ductwork in a space. Currently we have to spend a lot of time adjusting Floor Plan Display of objects in their model after it's been opened in Archicad. And we need to re-do it every time we get an updated model.
Graphic attributes like pens and fills we can handle with Graphic Overrides, but the Floor Plan Display thing is tough.
