Profile measurements
Profile measurements compare part features acquired by crosshair or optical edge probing to nominal part
profiles from drawing or part data files. Measured features and nominal profile features are shown in the
Measure Profile window.
NOTE
Comparator crosshair images are shown throughout this section to illustrate the vari-
ous aspects of profile measurement. However, the concepts apply equally well to opti-
cal edge detection and other measurement technologies.
The nominal profile in the Measure Profile window can be imported from a drawing file in .IGS or .DXF
formats, or as a collection of features from the Features template.
As features are measured, their points can be displayed in the Measure Profile window. When the de-
sired points have been probed, a
Fit operation can be performed.
During the Fit operation, the sys-
tem superimposes the measured
data over the nominal profile and
adjusts the X, Y and rotational
orientation of the data to achieve
the best fit. Data points can be
shown as dots and form errors can
be shown as whiskers.
