Rotating and Offsetting a Reference Frame The M3 reference frame can be rotated and offset to accommodate custom measurement applications.
Rotating the Measurement Reference Frame The measurement reference frame can be rotated about the part datum in clockwise or counterclockwise directions and in angular increments as small as one second or 1/1000 of a degree depending on a unit of measure being used. To rotate the measurement reference frame: 1 Press the Rotate Coordinates button of the Datum menu Measure toolbar > Datum menu > Rotate coordinates button
2 Enter the desired angular rotation value into the Angle field. Clockwise angles are positive, and counterclockwise angles are negative. 3 Press the done button to complete the reference frame rotation. A rotation feature will be added to the Feature List. Measure toolbar > Done button
Enter the desired rotation angle and press Done
Reference frame rotated
To reset the reference frame to the original rotation:
1 Delete the rotation feature from the Feature List. 2 Repeat the process described above but enter a skew rotation equal in value but opposite in polarity to the initial Skew Rotation value. 3 Offsetting the Skew Alignment The skew alignment can be offset from the X or Y coordinates by increments as small as one micron or 1/10,000 of an inch depending on the unit of measure being used. To offset the part skew alignment: 1 Measure two features that will determine the skew offset. Make a note of the X and Y values of each feature. These features will be referred to as Feature #1 and Feature #2 in this procedure. During the procedure, the user will specify offsets from these two features to the skew axis. The system will then construct a line between the two features which will be used as the new part skew alignment. 2 Press the Offset Skew button of the Datum menu Measure toolbar > Datum menu > Offset Skew button
