Step 2: Enable the Relative Level Tool

  1. Open the Asset Panel, click the dropdown menu in the top-right corner of the annotation panel (currently showing "Annotation Detail").
    ​

    a. Place Relative Plane:

    • Right-click on the model to place the relative plane at that point's elevation.

    • You can also right-click and drag the relative plane to move its position manually.

    Note: You can position this plane at ground level, roof level, or set it to any arbitrary datum.
    ​

Step 3: Set Reference Level

  1. Position the Plane: Move the plane to ground level (or your preferred reference).
    ​

  2. Establish Relative Level Value: Click to set this point as your reference level. If you are using a known datum, enter the appropriate value for that datum.

  3. Save Settings: Once satisfied, click Save.
    ​

Step 4: Measure Relative Elevation

  1. Exit Relative Level Tool: Close the tool to return to your previous position.

  2. Start Drawing Again: Right-click, select Start Drawing, and click Finish.

  3. View Elevation: The elevation value will still be displayed, but now you can also see the Relative Level Elevation.
