BIM 360 Layout: Set up a robotic total station on a known point

The Autodesk® BIM 360TM Layout app for iOS and BIM 360TM web service provide vertical construction contractors the ability to connect the coordinated model to the field layout process.

BIM 360 Layout: Set up a robotic total station on a known point

Robotic connection

A connection between Autodesk® BIM 360TM Layout and the robotic total station must be configured before starting the total station setup procedures. A full and detailed explanation can be found in these myTopcon articles: 


Total station setup

  1. Set the total station on a tripod and secure with the mounting screw.
  2. Use the optical or laser plummet to align the total station with the control point.
  3. Level the total station with the digital level and the tribrach leveling screws. Or, if equipped (LN-100), allow your instrument to self-level.
  4. Check the plummet for alignment with the control point, and use the mounting screw to adjust, if necessary.
  5. Re-level with the digital level, and check the plummet again.

Setup routines

Before you can use a total station on a jobsite, you need to complete a setup routine, which completes the orientation of the total station equipment with the BIM information and the jobsite. Without a completed setup routine, the total station has no idea where it is in the world.

    Known point setup

    This routine is used to check control points and set up your total station. Occupy a known control point with the total station, and backsight to another known control point.

    1. Having selected a model, in the Home view, click on the Layout  icon.
    2. New icons are now available in the top ribbon. Click on the New Setup  icon.
    3. In the New Setup menu, click Known Point.


      The setup process in BIM 360 immediately asks for both instrument (robotic total station) height and target height.

      1. Measure and type the instrument height.
      2. Click Next.
      3. Measure and type the target height.
      4. Click Next.

      Control points

      Select the control point where you are setting up the total station, either from

      1. the list,
      2. from the map view, or
      3. by typing the point number.
      4. With the selection made, click Next.
      5. Select the control point for orientation.
      6. Click Next.

        Setup complete

        Once the total station measures the orientation point, an overview of residuals—the difference between model and actual measurement—is shown. If the values are within the defined tolerances, conclude the process. If not, return one step back and repeat the measurements. 

        1. Click Done to conclude the setup process.
        2. As a good practice, you are advised to measure and save the data to the used control point. Click OK.




        In the control verification screen, with the total station locked on the target:

        1. Collect the checked measurements.
        2. Save the measurement, defining the point Name/Number, Role, and Type.

        The setup process is now concluded, and the total station is ready to be used in BIM 360 Layout.
