The Point-Line measurement calculates the deviation of a point relative to a line.

Input requirements:

Measure Type: Point to Line

Geometry Requirement: 3 point

Direction Mode: True Distance, Projected on Plane

Direction: (Projected on Plane)

Output:

Direction Mode: True Distance

The measurement calculates the perpendicular distance from the line to the point. The measurement cannot be negative. No direction vector applies. This mode may produce incorrect Contributor Analysis or GeoFactor Equation-Based results, see Analysis Comparison & Assumptions.

Direction Mode: Project on Plane:

Two direction vectors are required. The measurement creates a vector at Pt1 using Dir#1. This vector and point Pt1 are projected onto a plane created with Dir#2. The measurement next projects the line created by LnPt1 and LnPt2 onto the plane defined by Dir#2. The measure is the distance from Pt1 to the line along the projected vector using Dir#1, as viewed from Dir#2. If Dir#1 and Dir#2 are in the same direction, Dir#1 forms a point on the projected plane, so the measured result will be zero. This mode may produce incorrect Contributor Analysis or GeoFactor Equation-Based results, see Analysis Comparison & Assumptions.
