Adjusting the bridle configuration

Once a bridle is inserted in the drawing, if the default configuration does not meet your needs, you can adjust how each leg is configured. Add and remove parts from the Basket Parts and Leg Parts lists to achieve the required dimensions, displayed in the Bridle Geometry diagram. The configuration depends on the list of Available Parts, which can be edited when Managing bridle parts.

1. Select the bridle, and click Bridle Configuration from the Object Info palette.
