BRA Area

Area helps to Create BRA Areas based on the Room Property “Department” and Wall Type Property “Function” (Exterior). This is a combination of “Area Boundary Lines” and “Areas”. There is an option to create the “Areas” or just “Area Boundary Lines”. Use the correct “Wall Function” (Exterior/Interior) and same value for Room Property “Department” for rooms that form one department. Manually adjustments of “Area Boundary Lines” can retain while running the function more than one time on the same view.

  1. Create an “Area Plan”

    This can be any kind of custom made Area Plan, in the AreaCriterias dialog from the Area Tool all Area Plans will be available from the drop down menu “View Name”.
  2. Select the Area Type and Levels

  3. On the question for automatically creation of boundary lines choose “No”

  4. Press “Area” on the Naviate Architecture ribbon panel and choose “Create BRA Areas”

  5. Select Level and View Name, optional whether or not to create “Areas” based on Room Property “Department” and press Apply

    When creating areas a dialog with the results will come up

    The Areas that are created get the department name as the Area Number
  6. If required, manual adjustments can be made
    - Unpin the “Area Boundary Lines” that require adjustment
    - Stretch, delete and add “Area Boundary Lines”
    - When running the “Area Tool” again on the same View, these options will be available

    Choose the options required and press OK

 The rules that are used when creating Area boundary lines.

There are two properties that effects the result of the application.

  • "Department" which is a property of rooms.
  • "Function" which is a type property of walls.

Rooms are the object that the function primarily is looking at. For each room the application looks at the room bounding walls and applies the rules. No Area Boundary lines are drawn where there are no rooms on either side of the wall.

Exterior Walls (type property "Function" set to "Exterior") are room bounding.

  1. Boundary lines are always drawn at near face of the wall.
  2. Room property "Department" have no effect if the wall is exterior. 

Other Walls (type property "Function" set to anything but "Exterior") or Room Separation Lines are room bounding.

  1. No boundary lines are drawn when there are rooms on both side of the wall and both rooms have the same department assigned.
  2. Boundary lines are drawn at near face if there is room on the other side of the wall with another department assigned.
  3. Boundary lines are drawn at center of the wall if there is no room on the other side of the wall.

The rules that are used when updating Area Boundary Lines.

The application uses the pin-function but in an opposite meaning. (The method is somewhat similar to the way pin is used when editing curtain walls/roofs/systems.) When the application creates an area boundary line it automatically "pins" the object. A user who wants to move a pinned object must "unpin" it. When a user creates an object it is not pinned. This is the logic behind the rules that the application follows.

  • Pinned Area boundary lines are assumed that they are made by the application.
  • Unpinned Area boundary lines are assumed that they are manually created or updated by the user.

When updating all pinned Area Boundary lines are first deleted and then again new are created according to the rules. Select if the unpinned (manually created or manually edited) should be kept or deleted.

The rules that are used when creating Areas

The application looks at the Department parameter and creates one Area for each unique value assigned to the parameter. The Area is placed aligned with the first Room found with a certain Department value. The Department value from the Room will be the number of the Area.
