      Measurement Tools in Aura

      The Measure Tools in Aura enable you to interact directly with the point cloud to obtain accurate spatial information. They are valuable for inspections, validation, and for communicating key dimensions directly within the 3D environment.

      Aura includes three measurement tools

      • Measure Point to record the coordinates of a single point.

      • Measure Line to calculate the distance between two points.

      • Measure Angle to determine the angle formed by three points.

       

      The Measure Tools are accessed from the Main Toolbar, located at the top of the Aura interface.

       

      When a measurement tool is active, Aura displays the full resolution of points around the cursor, enabling accurate point selection. To maintain a performant user experience, points further from the cursor are not displayed. The size of the loaded area adjusts automatically based on the camera position and the current point budget setting.

      Measure Point

      The Measure Point function records the location of a single point in the point cloud. When selected, Aura displays an information label showing the point name and its X, Y, and Z coordinates in the project’s coordinate reference system.

      Measure Line

      The Measure Line function calculates the distance between two points.

      1. Select a starting point (A) and then an ending point (B).

      2. Aura displays labelled markers at each point and generates an information label showing the measured distance and the assigned measurement name.

      Measure Angle

      The Measure Angle function calculates the angle formed between three points in 3D space.

      It is useful for analysing changes in direction, slopes, or intersections within the scan.

      1. Select the first point to define the start of the first line segment.

      2. Select a second point to define the vertex (the central point of the angle).

      3. Select a third point to define the end of the second line segment.

      4. Aura displays labelled markers for each point and generates an information label showing the calculated angle at the vertex and the assigned measurement name.

       

      Managing Measurements

      All measurements appear in the Visualize tab and are grouped by type: Point, Line, or Angle. They are named sequentially within each type based on the order of creation.

       
      From the Visualize tab, you can also control measurement visibility. Use the view icon
      To hide a measurement, or the remove icon to delete it permanently.

      Deleting a measurement does not reset the sequence. For example, if Point 2 is deleted, the next point created will still be named Point 3.

       

      Measurement Details

      The Measurement Details panel provides additional information about a selected measurement. It displays the point’s X, Y, and Z coordinates along with contextual values, depending on the type of measurement:

      Category Option Description
      Point X, Y, Z coordinates The location of the selected point.
      Line Line length The true 3D distance between two measured points.
      Horizontal The distance between the points in the horizontal plane (X–Y), ignoring elevation.
      Vertical The difference in elevation (Z) between the points, ignoring horizontal distance.
      Coordinates The X, Y, and Z values of both endpoints.
      Angle Magnitude The measured angle between three selected points.
      Coordinates The X, Y, and Z values of all three points.

       

      The Measurement Details panel can be viewed by selecting a measurement in the Visualize tab. The details then appear in the Properties panel on the right-hand side.
