Set Viewpoint From Instrument Updates

The graphical viewpoint within the job file can be updated dynamically based upon the current probe or scanner position and orientation. This enables the capability to “fly around” a part using an instrument, or to update the viewpoint while measuring such that the probe is always visible in the graphics.

To Enable the Viewpoint Based on Instrument Updates:

Enabling the Instrument View

At the top of the Instrument View dialog is an optional check box to Enable Viewpoint from Instrument. This is the on / off control for the view control. When enabled, graphical position updates from the selected instrument will be used to update the graphical view using the selected settings below.

Instrument selection is not necessary if only a single connected instrument is available in the job file. However, if more than one live instrument is available the controlling instrument must be selected using the ellipsis button.

Configurations

Probing Controls

3D Probe Users (Laser tracker and total stations) When measuring with only a reflector the instrument does not provide enough information to control the direction of the view in the graphics. However two options are available.

Scanning Controls

Graphics Updates

View Orientation Reference Frame

The instrument view uses the selected frame to control the vertical orientation of the display. By default it expects the Z axis of World frame to represent the gravity direction and orients the graphics accordingly. If you wish the view to be at a different angle, a different frame can be selected.

Example Use Cases:

  1. Measuring with a Laser Tracker and an 1.5" SMR.  In this scenario the only control you need is an ability to keep the reflector within the graphics. You may also want to check the box to Automatic Zoom when Trapping. This allows the view to zoom out to encompass the nominal target and the allows the zoom to increase as you move the probe closer to it. It also helps to more precisely measure that feature.

  2. Measuring with a 6D probe, such as a T-probe. In this case the view is set by the probe such that the user is looking straight down the probe tip. A 6D probe can also be used as a navigation device that cuts through features in the graphics showing those objects behind. To do so use the Click Behind Probe option.

  3. When Point Cloud Scanning. When scanning a point cloud a slightly different
