             | The dialog box opens: |  
             |  | 
       Enter a value in the 
       Diameter field. The Section is automatically computed.As an alternative, you can enter the 
       Section, the Diameter will be computed.
 
         
           
             | 
              | The bend radius must be at least equal to the Diameter 
             value to insure the correct bundle segment route computation. A 
             message warns you if it is not the case. | 
       Enter a value for the 
       Bend Radius.The Bend Radius is the minimum bend 
       radius allowed for the bundle segment.
 As an alternative, you can select the Bend Radius Ratio 
       option and set the ratio: the Bend Radius 
       is automatically computed.
       Select the Mode: 
         
           | The different options are: 
             Slack:the bundle segment length is increased by the percentage indicated 
             in the Slack(%) field. The Length field is 
             disabled.
Length:the bundle segment length is indicated in the Length 
             field. The Slack(%) field is disabled.
Bend:the bundle segment length corresponds to the minimum distance 
             between the points defining its route. The  Slack(%)
             and Length fields are disabled.
 |  At this stage, the bundle 
       segment parameters are defined.You now need to route the bundle segment to be able to complete the 
       definition: through this operation, you will create the geometrical 
       representation of the Flexible Curve.
 Note that OK and Apply are deactivated.
       See the
       next task which explains how to route the 
       bundle segment according to the geometrical constraints. |
