Information about the rooms between dRofus and softwares that supports IFC can be exchanged with the IFC support in dRofus. This is done primarily by three procedures:
Connecting the room in dRofus to the IFC model
Synchronizing with the model
Importing rooms from IFC
The first point means that you either create an empty model or synchronize data, or that there is a CAD/DAK model exported to IFC that you can connect to.
When you synchronize with a model, all dRofus information is updated in the model and information about the model will also be able to update the room program with projected data (see Create New, Edit or delete IFC Attribute Configuration ).
If the IFC Fails to connect check the Connection Between Rooms in the Model and Room Program
