With the emergence of BIM (Building Information Modeling), the need arose for independent software standards for securing the model information. Thanks to the "open standards" - accessible to everyone - the BIM-process can be structured and streamlined. The Revit Standards are open standards for Revit-users. The Revit Standards Foundation manages these standards.
Various BIM platforms can communicate with each other thanks to open standards. The Revit Standards are open standards for Revit-users.
