The Industry Foundation Classes (IFC) format is an open international standard for Building Information Model (BIM) data that is exchanged between different software applications. This data describes a building or facility, including spatial elements, materials and shapes.
See buildingSMART for more information about the specification.
You can serve the IFC data from LuciadFusion using the OGC 3D Tiles protocol. You can serve the attributes of the IFC elements from LuciadFusion through a WFS service. You can also open the data directly in LuciadLightspeed, although this is not recommended due to a large memory footprint and high CPU load.
