The Plane-Nominal measurement is based on the deviation of a plane relative to its nominal orientation.

Input:
Geometry Requirements 1 Plane (3 Points)
Measure Type | Plane-Nominal |
Direction Mode | True Angle, Projected on Plane |
Direction | Required for: Projected on Plane |
Output:
Direction Mode: True Angle
The measurement calculates the true angle between the nominal and deviated orientations of the plane. The measurement will be between 0 and +180 degrees. No direction vector applies. This mode may produce incorrect Contributor Analysis or GeoFactor Equation-Based results, see Analysis Comparison & Assumptions.
Direction Mode: Projected on Plane
The measurement calculates the true angle as it is viewed from the direction specified. The measurement will be between -180 and +180 degrees. The measurement will be negative if the angle between the direction vector and the cross product of the two plane vectors is more than 90 degrees.
