The position data points P1 to P3 in absolute dimensions relative to the zero point are the
following:
P1: X20 Y35
P2: X50 Y60
P3: X70 Y20
Incremental dimensions
In the case of production drawings in which dimensions refer to some other point on the
workpiece rather than the zero point, it is possible to enter an incremental dimension.
When incremental dimensions are entered, each item of position data refers to a point
programmed beforehand.

The position data for points P1 to P3 in incremental dimensions are:
P1: X20 Y35 ;(referred to the zero point)
P2: X30 Y20 ;(referred to P1)
P3: X20 Y-35 ;(referred to P2)
