Autodesk is deeply involved in openBIM and the IFC Standard since the creation of buildingSMART formerly International Alliance for Interoperability in 1995.
In order to facilitate the life of million of Professionals using our solutions integrating IFC & COBie interoperability import and export capabilities, Autodesk has written a Revit IFC Manual which will explain you all the capabilities, workflows, best practices if you want to be very efficient with Revit’s openBIM capabilities.
This document is intended to serve as a guide for Revit users handling IFC data and providing a better understanding of the settings available in Revit, discussing the way they can influence the quality and the content of the IFC file. The Revit IFC manual therefore sets out the basics of IFC and explains in detail how to export, link and open IFC files in Revit.
You can download this manual from here.
Some specific versions in French and Italian will follow soon.
