If the IFC model contains IFC spaces that are linked with the rooms in dRofus, according to the Room <-> IFC Room configuration, the sync operation will place the occurrences in the linked rooms Items list. In the image above you can see in the first column that some of the imported occurrences have been assigned a room relation. There are some prerequisites in the IFC model for connecting occurrences to rooms to work.
Rules for connecting occurrences from IFC to room equipment lists in dRofus:
The IFC model used for importing / syncing occurrences must contain IFCSpaces that are linked with the rooms in dRofus
The Objects in the IFC file must have a relation to the IFC Space, not only e.g. IFC Story or IFC Building
The equipment list for the room must have following statuses in order to connect the occurrence to the room equipment list;
Not created
Unique
Derived
Rooms with equipment lists coming from a room template or equipment template will not be updated from IFC. The occurrences will need to be connected manually after import.
