How to Adjust Room Boundary in Revit?

Understanding Room Boundaries in Revit

Adjusting the room boundaries in Revit is essential for accurate space planning and area calculations. The room boundary defines the limits of a room that Revit uses to compute space properties such as area and volume.

Step-by-Step Guide to Adjust Room Boundaries

1. Access the Architectural Settings

To begin, navigate to the Architecture tab located on the main ribbon of Revit. Look for the Room & Area panel and click on the drop-down arrow next to it.

2. Configure Area and Volume Computations

From the drop-down menu, select Area and Volume Computations. This opens the corresponding dialog box. On the Computations tab, you will find settings related to how room areas are calculated.

3. Choose a Room Area Computation Method

Within the dialog box, locate the section labeled Room Area Computation. You will notice various options available. Selecting the appropriate method is key:

• At wall finish: This setting places the room boundary at the finish face of the wall. This is advisable for interior spaces where the wall finish represents the room’s usable area.

Once your selection is made, click the OK button to apply the changes and exit the dialog box.

4. Create or Modify Room Boundaries

If you need to create or modify existing room boundaries, use the Home tab. Under the Areas section, select Area Plan to initiate the boundary creation process. Here, choose “Room Areas” for the plan type. You will be prompted to create boundaries for your interior gross area; select No to indicate that room boundaries should be drawn without extraneous lines.

Next, use the Area Boundary Line command to draw boundaries around each wall that you wish to define as a room boundary. Make sure to closely follow the walls for precision.

Verifying Room Boundaries

To determine if the elements you’ve defined are acting as boundaries in Revit, select the linked architectural file. Open the Modify RVT Links ribbon and click Type Properties. Check the Room Bounding parameter to ensure it is active. This confirms the elements are being utilized as boundaries for room calculations.

Hiding and Deleting Room Boundaries

If necessary, you can hide or remove room boundaries that are no longer needed.

• To Hide a Room Boundary:

  1. Open the desired view (plan or 3D).
  2. Access the View tab and select Visibility/Graphics.
  3. In the Model Categories section, find and expand Lines.
  4. Check or clear the box next to Room Separation to make the boundaries hidden or visible as needed.
• To Delete Room Boundaries:
  1. Start by creating a room schedule if one does not already exist.
  2. Open the room schedule within the drawing area.
  3. Identify the row corresponding to the room boundary you wish to remove. Click inside this row.
  4. To delete multiple room boundaries, click on the Modify Schedule/Quantities tab, and choose Delete.

Frequently Asked Questions

What defines a room boundary in Revit?
Room boundaries are defined by the physical elements within a model, such as walls, floors, and ceilings. When these elements are set to be Room Bounding, they are recognized by Revit for area computations.

How can I check if a room boundary is set correctly?
To verify a room boundary, select the room and observe if its area populates correctly in the properties panel. Additionally, you can visually inspect the boundaries in the view to ensure they align with the walls.

What happens if a room boundary is not set correctly?
If room boundaries are not configured properly, the computed area and volume may be inaccurate. This can lead to insufficient space planning and unexpected results in schedules or area calculations. It’s vital to check and adjust boundaries regularly during the design process.
