Creating Twin Joggles

This task explains how to create twin joggles on a web or a surfacic flange.
A twin joggle is a feature embedding two joggles with the same depth value and direction, and opposite runout directions. You can create a twin joggle on a closed surface or inside another twin joggle.

Create a web with a surfacic flange and two planes.

  1. Click Twin Joggle in the Aerospace Sheet Metal toolbar.
    The Twin Joggle Definition dialog box appears.

     

  2. In the Support box, select the surfacic flange or the web.

  3. Select the planes for both joggles.

    The twin joggle is previewed:
     

  4. Define the twin joggle type:
    1 corresponds to Joggle 1 and 2 to Joggle 2.

    • Outside Planes :
       
    • Inside Planes :
       
    • Outside / Inside Planes :
       
    • Inside / Outside Planes :
       

  5. Optional: To define a compensation, select the Apply compensation check box.
    For more information, see Creating a Joggle.

  6. Define the offset type and parameters:

    • Depth:
      • Enter the gap value between the support surface and the joggle offset surface.
      • Reverse the depth direction either by clicking Invert Depth Dir in the dialog box or the red arrow in the 3D area.
    • Offset Surface: Select an offset surface.
      For more information, see Creating a Joggle by Selecting an Offset Surface.

  7. For each joggle, define the following parameters:

    • Runout: Length of the joggle area.
    • Clearance: Gap between the joggle plane and the end of the joggle area.
    • Start Radius: Radius value at the start of the joggle area.
    • End Radius: Radius value at the end of the joggle area.
    • If you modify the depth, the runout adjusts automatically by using the formula applied to the runout parameters. To manually modify it, right-click the Runout box, and select Formula > Deactivate.
    • If the support is a closed surface, the Invert Twin Joggle Dir. button and an arrow appear in the dialog box and in the 3D area to reverse the direction of the twin joggle.

  8. Click OK.
    The twin joggle (identified as Twin Joggle.xxx) is created.

    Two twin joggles cannot intersect, and a single joggle cannot be created inside a twin joggle.
