Constructing a datum zero point
The datum zero point can be constructed from parent features when simply probing the desired point is
not practical.
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 icon.
