Arc Properties
Radius measure the radius of the Arc.
Circularity ratio of the smallest diameter to the largest diameter, sampled around the Arc.
Min minimum radius measured.
Max maximum radius measured.
Std.Dev. Standard Deviation calculated for all radius values measured.
Fraction percent of samples that detected an edge, (number of “sucessful” samples divided
by the total number of samples (accuracy number) multiplied by 100).
• Enable – check this box to report a measurement and pass or fail the part on this measurement;
or clear this box to not report a measurement and not pass or fail the part on this measurement.
• Relative – clear the box to report actual numbers; check the box to report difference.
• Auto label position – puts the label (AR1, ACr1) beside the curve in the display. Clear the
check box to move the label to another location (or with the Properties box closed, drag the
label).
• Locator – makes the tool follow the Locator, and follow the part. Select a locator (by number)
to follow, or select “X” to disconnect the tool from the locator, or make the tool stay in a fixed
position in the image area.
• Accuracy – number of sampling points around the curve; indicated by the pink dots and radial
lines.
• Show center point – displays the point at the arc center, and allows you to use it in other mea-
surements.
