Hoping someone can help me out here. I am using a face based fan filter module family in my MEP model. The FFM's were placed in an RCP and show up correctly in my model. When we swap models with the architect, however, all of the FFM's are showing up "upside down". I suggested they flip the workplane, and that fixed the problem. Unfortunately they aren't happy with having to flip the workplane every time we do a model exchange. From what I can tell, there is nothing wrong with the family. If I flip the workplane in my model, the FFM's show incorrectly. Is there some issue with linked models that I am unaware of? Any thoughts would be greatly appreciated.
