Displaying the Probe Path
For all Measure steps, you can display the probe path and a simulation of the probe, to verify the probe path and make a visual check for interference with fixtures and model features. For Construct steps, the Constructed entity is highlighted. For Verify steps, displaying the probe path will make the system display the verified dimensions or geometric tolerances. You can display the probe path for individual steps or for a whole operation.
The configuration option cl_arrow_scale allows you to control the size of the probe path arrow. The default is 1. If you set it to 0, the arrows will not be displayed. Specifying any other positive number will scale the arrow accordingly.
