User manual Version 9.4, November 2009 PRIMER Setting the Fold Angle The Angle popup button can be used to select the angle of the fold. In this diagram the current fold angle is 0º . The popup contains default fold angles of 0, 45, 90 and 135º . Most folds will take place in either the X (0º ) or Y (90º ) directions, but if necessary, you can use Custom angle to set the fold to an arbitrary angle. If a new fold angle is chosen the graphic on the Angle button will be updated so you can easily see the angle of the current fold. 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. Setting the Fold Direction As well as setting the fold angle, the direction in which the fold is done needs to be set. In the adjacent figure the fold angle is set to 45º (you can tell this because of the angle of the yellow line). The graphic shown for the direction of the fold is also drawn at the 45º angle but there are two possible ways to do this fold The upper right part of the airbag can be folded onto the lower left part of the airbag (Forward). The lower left part of the airbag can be folded onto the upper right part of the airbag (Reverse). You can select the fold direction by choosing either Forward or Reverse. The graphic on the Direction button will change to indicate your selection. Page 6.41
