Defining a Transition Zone

This task shows how to create a transition zone defining the geometric area of the ply drop-off between two zones.

Available in Composites Engineering Design (CPE).
Open the TransitionZone1.CATPart document.
  1. Click the Transition Zone icon .
    The Transition Zone Definition dialog box is displayed.

  2. Select a zone in the specification tree or in the 3D geometry.
    It is displayed in the Underlying zone field on which the transition zone lies.
    A name is given to the Transition Zone that you can modify.
    In our example, we changed the name to T1-1.

  3. Define a contour by selecting curves so that they form a closed contour.
    A green tip replaces the red cross.

    Use Insert After, Before and Remove to modify the order of the curves as well as the contour.
    This contour must belong to the zone.
  4. Click OK to create the transition zone.
    The feature is displayed in the specification tree under the Transition Zone node.

    You can create several transition zones between two zones.
  5. Perform this scenario as many times as you need to create transition zones.
    In our example, we created ten transition zones in Zones Group.1, each zone containing one contour; and four transition zones in Zones Group.2, each zone containing one contour as well.

Should you need to create the curves for the transition zone contour, right-click in the Contour field and create the element you need.
