Quick Start

Creating part skew and datum references

When the part is misaligned (twisted) in the X-Y plane, errors can be generated during the measurement

process. These errors can be eliminated by creating a skew alignment for the part.

The skew alignment includes a precise measurement of the part misalignment. Once the misalignment is

known to the system, subsequent feature measurements are automatically compensated to eliminate mis-

alignment errors. Measurement data in the DRO will reflect measurements of a perfectly aligned part.

Creating a part skew

To skew the part:

1 Touch the Skew/Level Mea-

sure icon.

2 Perform the skew alignment by probing 2 or more points well distributed along the entire length of the

desired part reference edge. Press the Enter key to enter each point. Press the Finish key to complete the

Skew measurement. The skew line feature will be added to the Features list in blue.
