Creating Variable Radius Fillets

Variable radius fillets are curved surfaces defined according to a variable radius. A variable radius corner means that at least two different constant radii are applied to two entire edges.

Before you begin:

Open a 3D shape representation.

  1. From the Refine or the Essentials section of the action bar, click Edge Fillet .
    The Edge Fillet.x dialog box appears.
  2. In the Edge Fillet Definition dialog box, click .
    Options for variable fillet creation are displayed.
  3. Select an edge.
    The selected edge appears in the Object(s) to fillet box. The app displays the radius value.
    Tip: The icon available in the Object(s) to fillet box, lets you edit the list of the faces to be filleted.
  4. In the Control points box, select the required control points.

    You can select the points:

    • On the edge, on the fly
    • Which are previously defined
    • Using cutting planes
    • Vertices
    Note: To remove a point from the selection, select the point again. You can add as many points as required.

    The app detects both vertices of the edge and displays two identical radius values.
    Note: The selected edge must be an open edge. You can define variable radius fillets on closed edges.

  5. Select the required point, and in the Active radius box, define the required value.

    You can also use the handles to change the radius value.

    The radius value is displayed on the selected point.
  6. From the Propagation list, select the required option.
  7. For each point, you can specify different radius value.

  8. From the Variation law list, select the variation law. For more information about variation modes, see About Variable Radius Fillets.
  9. Click OK .

    The edge is filleted. The tree indicates this creation.



  10. To edit this fillet, double-click EdgeFillet.x in the tree.
  11. Click Options for additional information.
  12. Click the Limiting element(s) box and select the required limiting plane.

    An arrow appears on the plane pointing to the portion of material that is kept.



  13. Optional: Click this arrow to reverse the direction.
  14. Click OK.

    The variable radius fillet is trimmed up to the limiting plane.
