To view your federated model in StreamBIM, you need to upload IFC files from the different disciplines in your project. StreamBIM is a big supporter of the open BIM Standards from buildingSMART. You can read more about open BIM standards here.
We also support uploads of all file types to StreamBIM Capture and StreamBIM Documents, of which PDFs, JPEGs and PNGs can be viewed directly in StreamBIM. Other formats must be downloaded and opened in other applications
