3D-MC: Avoidance area in version 13

In 3D-MC, under Project Layer, there is an Avoidance option which allows you to set audible and visual alarms when within a user-defined proximity of the data within a selected layer. The types of data that can be used in a selected layer are points, lines, closed polylines, and surfaces. The data must be associated to layers using software like 3D-Office, MAGNET 3D Exchange, or MAGNET Office.

A project file (*.TP3) has various data and surfaces (road TIN surface, road alignment, SW TIN utility surface, stringlines, etc.) and each of these has a separate specific layer for it.

It is possible to configure the surface in 3D-MC so that an alarm sounds and changes color when the machine is above the surface, below the surface, above/below the surface, or outside the surface. This flexibility allows these surfaces to be used as containment rather than avoidance areas. The avoidance settings only get applied for the currently selected project. You can set them by navigating to Data > Layers, and then click Avoidance. Then, specify the avoidance parameters for each layer.

The same project file (*.TP3) that was created in 3D-Office is now loaded into 3D-MC.

The second image below shows a utility TIN surface under a road surface.

From the main menu, go to Data > Layers.

Click the Avoidance button to specify the avoidance parameters for each layer.

Scroll down to see all the layers in the project.

Select the layer to be used for the avoidance, then use the avoidance parameters for each layer by using the following three buttons:

  • Mode: Sets whether the layer is a 2D or 3D avoidance layer. If the layer is set to off, the entities on the layer are not used for avoidance.
  • Proximity: The distance of how close the machine can get to the entity in horizontal and vertical directions before the alarm will go off:
    • 2D mode is the horizontal direction.
    • 3D mode is the horizontal and vertical direction.
  • Surface Mode:
    • Off:  Any surfaces linked to the layer do not get used as an avoidance surface.

    • Above: If the machine is above the surface, the alarm is triggered.

    • Below: If the machine is below the surface, the alarm is triggered.

    • Above/Below: If the machine is above or below the surface, the alarm is triggered.

    • Outside: If the machine leaves the surface, the alarm is triggered.

In this example, the selected layer has settings where the mode is 3D, the proximity is 1.5 meters, and the surface is above.

You can see the avoidance function is working when the machine is above the 3D surface. The alarm is triggered, and the color has changed.
