3 Select the DRO window, and while the point feature is selected touch the X and Y axis Zero buttons

to establish a datum zero at the probed point. The datum point will be shown in blue.

Constructing a datum zero point
The datum zero point can be constructed from parent features when simply probing the desired point is

not possible.

It would not be possible to provide a single description of this process for all measurement applications

that require feature constructions to create a datum zero point. However, the concept illustrated by the

following example and the construction techniques described later in this chapter can be used to construct

a datum zero point for any measurement application.

In this example, after the part skew is performed, a datum zero point is constructed at the intersection points

of the X-axis along the bottom of the part (skew axis), and the Y-axis along the left side of the part.

To construct the datum zero point:

1 Touch the Measure Magic or the Measure Line
