In StreamBIM we create a 2D footprint(*) of the floor/building story, and use that as a navigation map. Which model layer you want to use is user defined, but will usually be a footprint of the Architectural model.
* By footprint we mean a projection of the IfcBuildingStorey
You can also define your own custom floor plan and use that as your 2D navigation map.
- Only uploaded pdf drawings can be used for custom 2D navigation map
- You can use one drawing per building Story
