Learn how room assignment types assign room names to predefined area definitions.
Each project standard requires particularly predefined room assignments in the appropriate language. These are defined by their project standard (the International Standard or a DIN standard).
- If the area calculation finds the room name in the file, the specific data is added to the tag.
- If no correspondence is found, the room gets applies the area assignment as not defined.
- Specify the correct room name when creating the Revit rooms.
- Make sure that the used room names are contained and correctly defined in the room assignment file.

Understand that upon area calculation, the room names are compared with the contents of the room assignments file and the equivalents are replaced. Areabook takes away the duty of manually assigning each room from you. Be aware that the Equivalents must be identical. For example, a room named Kitchen will be identified as Kitchen in the room assignment file. If another room is named Ap2 Kitchen, Areabook will not identify an equivalence and mark the room as not defined. You could still edit each room individually.
