You can manually edit room boundaries in Revit primarily by using the Room Separation Line tool.
Manually adjusting room boundaries is essential when automated boundary recognition isn't sufficient, such as when dealing with open spaces, specific design intentions, or when linking models.
Using the Room Separation Line Tool
The Room Separation Line tool is your main method for defining or adjusting room boundaries manually. This tool allows you to draw lines that act as virtual walls, preventing rooms from expanding past these lines.
Here's how you typically use it:
- Go to the Architecture tab.
- In the Room & Area panel, click on Room Separation.
- Draw lines in your plan view where you want to define or modify a room boundary.
These lines will act as boundaries for room placement and calculation.
Adjusting Existing Boundaries
Once you draw a Room Separation Line, you can select it and use the standard modification tools (Move, Copy, Rotate, etc.) or drag its grips to adjust its position and length, fine-tuning the room boundary as needed.
Considerations When Editing Boundaries
When manually editing room boundaries, keep the following in mind:
- Visual Check: Use a plan view to visually check the outer boundaries (perimeter) of a room. This helps ensure your manual lines align with your design intent and other room-bounding elements.
- Linked Models: As noted in the reference, when you link models together, by default Revit does not recognize room-bounding elements in the linked model. This is a common scenario where you must use the Room Separation Line tool to add and adjust room boundaries within your host model to accurately define rooms that span across or abutt elements from the linked file.
- Room Tags: After adjusting boundaries, ensure your room tags correctly identify the newly defined spaces. You may need to move or delete and recreate tags.
- Area Calculations: Manual boundary adjustments directly impact room area and volume calculations. Verify these calculations after making changes.
Summary of Manual Boundary Editing
| Task | Tool/Method | Key Benefit |
|---|---|---|
| Define/Adjust Boundary | Room Separation Line | Provides precise control over room limits |
| Verify Boundary | Plan View Visual Check | Ensures accuracy and alignment with design |
| Address Linked Models | Room Separation Line(s) | Defines rooms where linked elements don't bound |
In summary, the Room Separation Line tool is the primary way to manually control and edit room boundaries in Revit, especially crucial for open plans or managing boundaries in linked models.
