Example Model:

C:\Users\Public\Documents\DCS\3DCS_V5_8_1_0_4\3DCS CAD & Example Models\Reference Models\Measures\Plane to Plane

Input:

Measure Type: Plane to Plane Angle

Geometry Requirements: 2 Plane (6 Points)

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 two planes. 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.
