Gocator Line Profile Sensors: User Manual
How Gocator Works • 52
In both cases, alignment determines the offsets in X and Z. Alignment also determines the tilt (angle on
the X–Z plane, around the Yaxis) needed to align sensor data.
The adjustments resulting from alignment are called transformations and are displayed in Sensor panel
on the Scan page.
System coordinates are aligned so that the system X axis is parallel to the alignment target surface. The
system Z origin is set to the base of the alignment target object. The tilt angle is positive when rotating
from the X to the Z axis.
As with sensor coordinates, Y position increases as the object moves forward (increasing encoder
position). The orientation of the Y axis is unaffected by alignment.
For more information on aligning sensors, see Alignment on page 106.
Part and Section Coordinates
When you work with parts or sections extracted from scan data, a different coordinate system is
available.
Part data can be expressed in aligned system coordinates or unaligned sensor coordinates, depending
on the alignment state of the sensor. Part data can also be represented in part coordinates, in which the
