We`re using Inventor 13 to design all of our machines and products. Most of the models have to get simplified because of the file size so the architecture could eventually use the models in Revit. Whenever we use the Inventor 13 BIM Exchange tool to create a .adsk file, Revit wouldn't import all the material-settings correctly. The material overview shows all the imported materials as unassigned although we chose the shared material library for Inventor & Revit as we created the models in Inventor. So we end up not having the correct appearance for the material if we don`t assign all the materials to the library in Revit. Is this is a bug to be fixed or should it work properly?
