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. You can create a standard variable radius fillet using the Variable Radius Fillet command.

Before you begin:

To perform this task, create a cube.

  1. Click Variable Radius Fillet .

    The Variable Radius Fillet Definition dialog box appears.

  2. Select the open edge to be filleted.

    You can define variable radius fillets on closed edges. For more information, see Variable Radius Fillets Using Closed Edges. The application detects both vertices and displays two identical radius values. The icon available after the Edges to fillet box lets you edit the list of the faces to be filleted. For more information about that capability, see Editing a List of Elements. Optionally, click Preview to see the fillet to be created.



  3. Enter a new radius value to simultaneously change the radius of both vertices. For example, enter 12mm.

    The new radius value is displayed on both vertices. The preview is modified accordingly. You can use the radius value R=0 to create a variable radius fillet.

  4. Keep Minimal as the propagation mode you want to use.

  5. Click the Points box then a point on the edge to be filleted.

    The application displays the radius value on this point. Note that to remove a point from the selection, you just need to click this point. You can also add points by selecting planes. For more information, see the end of the task. You can add as many points as you wish.

  6. Enter a new radius value for this point: enter 4. The new radius value is displayed.

    This is your preview:



  7. The variation mode is set to Cubic: keep this mode. To see the Linear propagation mode, see More about Variable Radius Fillets.

  8. Click OK to confirm the operation.

    The edge is filleted. The specification tree indicates this creation.



  9. To edit this fillet, double-click EdgeFillet.1 in the specification tree.

  10. To access additional options, expand the dialog box by clicking More..



  11. Click the Limiting elements box and select Plane.1 as the plane that will trim the fillet.

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



  12. Click this arrow to reverse the direction and therefore specify that the portion of material to be kept will be the opposite one.

  13. Click OK.

    The variable radius fillet is trimmed to Plane.1. The final part looks like this:
