How do you cut a wall on an angle in Revit?

Published in Revit Walls 3 mins read

You can cut a wall on an angle in Revit by adjusting its angle using angular dimensions and reference planes. Here's a detailed process:

Steps to Angle a Wall in Revit

Revit doesn't directly offer a "cut at an angle" tool for walls. Instead, you adjust the wall's angle using dimensions and reference planes. Follow these steps to achieve angled walls:

  1. Prepare the Project:

    • Start by creating the wall you want to angle in your Revit project.

  2. Create a Reference Plane:

    • Draw a vertical or horizontal Reference Plane near the wall. This plane will serve as a reference for the angular dimension.
    • Having a reference plane allows you to accurately control and measure the angle you’re creating.

  3. Set up Precise Angular Dimensions:

    • Create a new Angular Dimension type using the following steps:
      • Go to Manage tab -> Settings panel -> Additional Settings drop-down -> Dimension Styles.
      • Click New.
      • Give it a descriptive name (e.g., "PreciseAngle").
      • Under the Units section, set the units to be very precise (e.g. 0.000000000001). This allows for highly accurate angled adjustments to your wall.
      • Click OK.
    • Activate the new dimension style.
    • Create an Angular Dimension using your reference plane and the wall as the references for the dimension.

  4. Verify Dimension:

    • Check the dimension and its properties to ensure the angle readout is correct, and that the angle of the dimension matches the desired angle for the wall.

  5. Adjust Wall Angle:

    • Select the wall.
    • Adjust the angle of the wall directly through the value of the angular dimension you created. Change the dimension, and the wall will reorient to match.

Practical Insights

  • Reference Planes are Key: The accuracy of your angled wall directly depends on how well placed and used your Reference Planes are.
  • Dimension Precision: Utilizing the new dimension type with high precision allows for very small, incremental changes. This is essential for highly accurate angled wall placements.
  • Flexibility: You can adjust angled walls later in your project using the same method, allowing you to refine your project layout as needed.
  • Angle Limitations: Consider architectural designs that use angled walls and the overall structure you intend to create. It is important to note that walls are typically based on vertical surfaces.

Example

To angle a wall at a 45-degree angle:

  1. Create a wall and a nearby vertical reference plane.
  2. Create an Angular Dimension between the reference plane and the wall.
  3. Ensure the Dimension is configured to use very precise units.
  4. Select the wall, then adjust the angle dimension to 45 degrees. The wall will rotate to this angle with respect to the reference plane.
