Circle Probe
The Circle probe uses edge detection to acquire many points along an edge each time it is fired.
The default of 90 points can be changed by supervisors, distributors and OEMs in the Probe
Library.
The Circle probe can be used to acquire points for circle and arc measurements.
Select the probe from the Probe menu,
the live video window on-screen
menu or the VED toolbar. Move the
probe, change its size or change its
orientation as described earlier in this
chapter.
Circles
To acquire points along a circle edge,
use Measure Magic or select a circle
feature measurement, select the probe
and position it over the circle and then
click the center mouse button to fire
the Probe.
The Circle probe can be created quickly using the
New probe in the live video window by clicking 3
points and dragging the third point across the edge to
be scanned.
When the New probe creates a Circle probe, the edge
order will automatically be made consistent with the
scan direction.
NOTE
Clicking the New probe in an arc
greater than 180 degrees creates a
full Circle probe. Clicking an arc
less than 180 degrees creates an arc
segment of the Circle probe.
