Following the completion of our Architectural Revit model we linked the Structural Engineers in to run a clash detection. One of the biggest 'clashes' has been my partitions running through the Steel, Steel however needs encasing in plasterboard and I haven't a clue how to do this. So far my only ideas are to do walls either side of beam with a ceiling between but that will be long winded and hard to be accurate. If anyone has done this before and can offer guidance it would be much appreciated.
