Before running the command, make sure that the key room parameters in your Revit project are filled correctly and that all rooms are placed in the model:

• Room Type :

  Room Type :

  The parameter value (by default, BMO_RoomType) should be “Living,” “Non-Living,” “Balcony,” or “Loggia,” so the command can correctly categorize rooms.

• Apartment Number :

  Apartment Number :

  The BMO_Number_Flat parameter (or another one specified in the settings) determines which apartment a room belongs to. For common areas, make sure building, section, and level values are set as needed.

• Placed Rooms :

  Placed Rooms :

  All rooms must have boundaries and be placed in the model (no “Room not placed” status). Otherwise, the calculation will not include them.

The "Update Flats" command can be found on the BIMO tab in Revit. Run it to have the plugin automatically calculate apartment and common-area spaces.

• Settings Dialog :

  Settings Dialog :

  If the plugin settings are not yet configured, the Rooming Settings window will appear. Verify the parameters, coefficients, and rounding precision, then confirm your changes.

• Automatic Calculation :

  Automatic Calculation :

  Once confirmed, the plugin gathers all rooms, calculates their areas (including reduction factors), and populates summary metrics (total area, living area, non-living area, number of living rooms, etc.).

• Completion :

  Completion :

  The command finishes automatically and may show a notification regarding success or potential issues. All data are then recorded into the room parameters specified in the settings.

To check the correctness of the calculations, open the Properties panel of any room and look at the parameters with the BMO_ prefix.

• Updated Parameters :

  Updated Parameters :

  The plugin populates each room’s area (BMO_RoomArea) and its area adjusted by the reduction factor (BMO_RoomArea*coeff), as well as the apartment’s total parameters (BMO_FlatArea_liv, BMO_FlatArea_liv+uninh+unheat, etc.).

• Schedules :

  Schedules :

  If you have relevant schedules (or create new ones), values for each apartment, entrance, floor, and so on become available for listing and filtering.

  If rooms or their types change in your project, simply run "Update Flats" again to refresh the calculated values accordingly.
