So, I'm sure most of us know by now what IFC are, if not, this post may be for you! I just wanted to make a small post to anyone who was still in the dark. IFC or Industry Foundation Classes are a data modeling standard which are complete and fully stable, open and international standards for exchanging BIM data. buildingSMART developed the idea and the certification process. 

I found this video a few weeks ago which showed one of the new features in the 2013 release of Autodesk Navisworks. This Autodesk Navisworks Learning video shows you how you can work with Revit models in Navisworks. You'll learn how to open Revit files in Navisworks, see how the Revit properties are imported with the model, and learn how to improve your workflows with the switchback functionality. This is one of the features in the 2013 which further aids the collaboration process between parties using different software packages.
