Creating Surfacic Flanges

You can create surfacic flanges on webs or on existing surfacic flanges, for instance a joggled surfacic flange.

When creating a surfacic flange, the bend is propagated along the whole base feature, with a tangent continuity.

Before you begin: Create a web.

In which cases the creation of a surfacic flange may not be possible?
  1. From the Model section of the action bar, click Surfacic Flange .

    By default, the Bend Radius type is Constant. It is set to the default bend radius of the part.

  2. Select the Bend Extremities type:
    OptionDescription
    Tangent The edges of the bend are tangent to the edges of the supporting features. This is the default behavior.
    Minimum The bend corresponds to the common area of the supporting features along the bend axis, and shows no relief.
    Note: This option allows you to create two surfacic flanges on the same support face as well as to create two surfacic flanges on two halves of a closed surface to create joggles afterward.
    Note: You can change the driving equation. To do so, click in the dialog box. The Formula Editor dialog box appears and you can then modify the dictionary and the parameters. You can also deactivate the formula: right-click the Radius box and select Formula > Deactivate before editing the value.
  3. Select the base feature.
  4. In the Support tab, define the geometric support.

    It can either be a surface, a plane, or a curve. Make sure the support is big enough to be able to later define an EOP with a length from OML.

    Important:
    • If there is no preview of the surfacic flange, it cannot be created.
    • The preview helps you build the surfacic flange, but the computation is only partial. For example, the computation does not include the relimitations of a surfacic flange.
    • You can modify the Support Length generated by the curve and the angle. By default, the length is 10 times the EOP (Edge of Part) length. If the default EOP length is higher than 100mm, you need to modify the surface length.
