Reference Plane & Face Scan
• The Reference Plane & Face Scan application program can be used to measure
points relative to a reference plane.
• A reference plane can also be scanned via Face Scan.
The Reference Plane & Face Scan application program can be used for the following
tasks:
• Measuring points to calculate and store the perpendicular distance to the plane.
• Viewing and storing the instrument and/or local coordinates of the measured
points.
• Viewing and storing the height difference from the measured points to the plane.
• Scanning a defined area.
Planes can only be computed with grid coordinates.
Reference planes are created using a right hand system. For two points defining a
plane a vertical plane is used. A reference plane is defined with the X axis and the Z
axis of the plane. The Y axis of the plane defines the positive direction of the Y axis.
A reference plane can be defined in the following ways.
• vertical
The axis of the vertical reference plane are:
X axis: Horizontal and parallel to the plane; X axis starts in point defined as
origin point
Z axis: Parallel to the instrument zenith and parallel to the plane
Y axis: Perpendicular to the plane; increases in the direction as defined
Offsets are applied in the direction of the Y axis.
