The Beta Angle of a SCTN defines the rotation around its U axis. The effect of changes to the Beta Angle are shown in the diagram below. The Beta Angle default is 0° which places the profile in the model in the orientation they are defined in the catalogue.

In this diagram the Justification Line is set to TOAX. Modifying the Beta Angle rotates the section around its U axis defined by the Justification Line.

Selecting Orientate > Beta Angle from the main menu toolbar allows the user to modify the Beta Angle in positive or negative increments of 90 degrees from the sub-menu.
