To view your federated model in StreamBIM, you will need to upload the IFC files from the different disciplines. 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 bookmarks 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
