Autodesk Research has been exploring the intersection of BIM (Building Information Modeling) and Internet of Things (IoT) for the last decade. Project Dasher (http://dasher360.com) integrates sensor data with model data from Autodesk’s Forge platform to contextualize IoT data in 3D. This session will look at the history of Dasher, as well as how some of its capabilities are now being integrated into Forge, allowing web developers to build digital twins integrating real-world performance data with 3D geometry.
