Defining an Arbitrary XY Fold Angle Using Custom Angle

The adjacent figure shows the box after pressing Custom angle. This allows the user to define an arbitrary fold line.

The angle may be selected in either of the following ways:

PICK LINE Calculates a line, and hence an angle from two screen-picked nodes.

Angle: Accepts a typed in angle, which may also be modified by [0] , [90] , [+90] , [-90] .

To accept the current definition press CHANGE , which will return to the fold definition menu.
