About the Creation of Folded and Unfolded Bends

This section provides information about the folding and unfolding options.

You can define the angle and radius types:

Type	Description
Angle	Corresponds to the angle of the selected face to fold or to unfold.
Angle type	Natural: the angle is set to the initial bend value by default and is not available. Defined: it allows you to choose the bend angle with the up and down arrows. Spring back: the angle of the bend is based on the natural angle with additional degrees. The natural bend angle and the angle value are manually defined.
Radius type	When you set the Angle type to Defined or Spring back, the following icons are available: Normal: it is the default option for the bend. Fix: the bending radius is the same and the position of the bending axis is fixed. Move: the bending radius is the same but the position of the bending axis moves.

This section provides information about the behavior of a bend when applying a partial unfold with the Radius type option set to Fix or Move .

• If you select the Fix radius type, the bending radius is the same and the position of the bending axis does not change.

  The following example is a partial unfold with the Fix radius type. The length of the Fix side (L1) is the same whereas the length of the move side (L2) has been increased by a correction length (Lc):

  The unfolded view is modified accordingly:

• If you select the Move radius type, the bending radius is the same but the position of the bending axis changes.

  The following example is a partial unfold with the Move radius type. The length of the Fix side (L1) has been increased by a correction length (Lc) whereas the length of the move side (L2) is the same:
