Appendix A
Profile measurement
Profile measurements compare part features acquired by video, touch-probe
or other measurement technologies to nominal part profiles from drawing or
part data files. Measured features and nominal profile features are shown in
the Measure Profile window.
NOTE
Video measurement tools are shown throughout these instructions to illustrate
the various aspects of profile measurement. However, the concepts apply
equally well to 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 Pro-
file window. When the desired feature measurements are complete a Fit
operation can be performed, During the Fit operation, the system superim-
poses the measured data over the nominal profile and adjusts the X, Y and
rotational orientation of the data cloud to achieve the best fit. Data points
can be shown as dots, form errors can be shown as whiskers.
