Description
Point which has been selected as origin
point.
The fall line is the line of greatest slope. The
fall line is a curve following the steepest
slope. It is always orthogonal to the contour
lines. The gradient of the height determines
the fall line mathematically.
The origin point and another point on the
reference plane define the orientation.
Available when Select a point of the plane
besides the origin point is selected. The
point which defines the orientation together
with the origin point.
Description
An offset is defined by a point or a distance.
The defined plane is shifted along the Y axis
by the offset.
