Line-Nominal

The DVTI_lineang Line-Nominal measurement is based on the deviation of a line relative to its nominal orientation.

Example Model:

C:\Users\Public\Documents\DCS\3DCS_All Platforms_8_0_0_1\3DCS CAD & Example Models\Reference Models\Measures\Line Nominal

 

 

Input:

Geometry Requirements: 2 Points

Measure Type: Nominal-Line

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 current orientations of the line.  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 angles 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 (Dir#1) and the two line vectors is more than 90 degrees.
