Reference Plane
The Reference Plane application is used to measure
points relative to a reference plane. It can be used
for the following tasks:
•
Measuring a point to calculate and store the
perpendicular offset to the plane.
•
Calculating the perpendicular distance from the
intersection point to the local X- and Z-axis. The
intersection point is the footprint point of the
perpendicular vector from the measured point
through the defined plane.
•
Viewing, storing and staking out the coordinates
of the intersection point.
A reference plane is created by measuring three
points on a plane. These three points define a local
coordinate system:
•
The first point is the origin of a local coordinate
system.
•
The second point defines the direction of the
local Z-axis.
•
The third point defines the plane.
P1
First point, origin of local coordinate system
P2
Second point
P3
Third point
P4
Measured point. This point is probably not
located on the plane.
P5
Footprint point of the perpendicular vector
from P4 to the defined plane. This point is
definitely located on the defined plane.
