Probing a circle

Two techniques can be used to probe a circle using the Multiple edge probe. The first technique is that

described earlier for probing lines and arcs and can be used to probe a circle whether the circle is com-

pletely within or outside the field of view. To probe a circle using the first technique with the multiple

edge probe:

1 Select the Circle feature

measurement, and then select

the multiple edge probe.

2 Seed the multiple edge

probe at 3 points evenly dis-

tributed around the perimeter

of the circle.

3 Move the stage to place the green arrow inside the

red circle. The remaining circle points will be probed

at roughly regular intervals around the perimeter of the

circle, the measurement will be completed and the fea-

ture data will be stored in the feature list.

4 The feature and probed points can be reviewed in detail by touching the View button if desired.
