I'm more concerned with figuring out why Revit is exporting the design line elements with extra nodes. I'm preparing a presentation to show how a customer can go from Revit to the Fabrication products, and the RIF file is creating duplicates in FABmep, ESTmep and CAMduct. The raw RIF file from Revit, when imported into ESTmep, shows the same splitting of linear pipe elements. Any thoughts on why Revit is doing this?
