Probing an arc
The same basic technique is used to probe an arc whether the arc is completely within or outside the field
of view. To probe an arc using the multiple edge probe:
1 Select the Arc feature measurement, and then select the multiple edge probe.
2 Seed the multiple edge
probe at 3 points in sequence
from the beginning to the end
of the arc.
3 Move the stage to place the green arrow inside the
red circle. The remaining line points will be probed at
roughly regular intervals along the length of the arc, the
measurement will be completed and the feature 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.
