Some up-to-date info on data exchange between Tekla and Revit, including IFC and SDNF workflows (from revit structure blog): The main purpose of the IFC import into Tekla is to allow the fabricator to accurately build a model from the consultants Revit model. However, you can convert certain objects from the IFC file to native Tekla objects such as beams, columns, footings etc. This is clearly useful rather than building a model from scratch. I tried this on a few beams and columns and again found no discrepancies with the original Revit Structure 2014 model, however, as you would expect the stairs translated to a bounding box. See the below image including the report. … I also imported an IFC model from Tekla to Revit with some fairly good results that are fine for coordination purposes. I would imagine that this may be better in a product such as Navisworks… … The best way to incorporate the analytical model from Tekla to Revit is to transfer the model as CIMsteel (Note that you will need to install the SDNF Import/Export for Autodesk Revit 2014). This gives you the option of transferring the analytical model
