Measurement Illustration
Width
Point-point: The difference on the X axis between the points.
Point-line: The difference on the X axis between the point
and a point on the line. For profiles, the point on the line is
at the same Z position as the first point. For surface data,
the point on the line is at the same Y position.
Point-plane: The difference on the X axis between a point
and a point on the plane with the same Y and Z coordinates
as the first point (or the intersection of the plane and a line
from the first point, parallel to the X axis).
Length
Point-point: The difference on the Y axis between the points.
Point-line: The difference on the Y axis between the point
and, for profiles, the nearest point on the line; currently,
always zero. For surface data, the point on the line is at the
same X position as the first point.
Point-plane: The difference on the Y axis between the point
and a point on the plane with the same X and Z coordinates
as the first point (or the intersection of the plane and a line
from the first point, parallel to the Y axis).
Height
Point-point: The difference on the Z axis between the points.
Point-line: The difference on the Z axis between the point
and, for profiles, a point on the line at the same X position
as the first point. For surface data, the point on the line is
the one nearest to the first point.
Point-plane: The difference on the Z axis between the point
and a point on the plane with the same X and Y coordinates
as the first point (or the intersection of the plane and a line
from the first point, parallel to the Z axis).
Distance
Point-point: The direct, Euclidean distance between two
point geometric features.
Point-line: The direct, Euclidean distance between a point
and the nearest point on the line.
Point-plane: The direct, Euclidean distance between a point
and the nearest point on the plane.
