Creating Auto Fillets

You can fillet and round the edges of a 3D shape in a single go.

Note: Depending on your role, you may not have access to this functionality.

About Auto-filleting
  1. From the Refine section of the action bar, click Auto Fillet .

    The AutoFillet.x dialog box appears.

    Tip: Optionally, click More to expand the dialog box and display images helping you define your specifications.
  2. From the Selection Type list, specify a computation mode between two possible ones:
    • Current solid: The whole current solid is filleted. This is the default mode.
    • Faces selection: The edges around the selected faces are filleted.
    Help images reflect the computation mode you select.
  3. In the Functional faces box, select the faces not to be filleted. The selected faces turn purple , indicating that they are not to be filleted.


  4. In the Fillet radius box, enter the required value for the fillet radius.
  5. Filleting applies to sharp edges that are not convex. This operation adds material to the 3D shape. Rounding applies to sharp edges that are convex. This operation removes material from the 3D shape. Because of mechanical reasons, a distinction needs to be made between filleting and rounding. The command lets you assign distinct radius values to the different edge types.

    By default, Round Radius check box is cleared. This means that if you modify the radius value, the round value is automatically modified and displays the same value as the radius value.

  6. Select Show curvature radius less than check box to display the fillets and rounds with radius value less than the radius value entered by you.
  7. Click OK to confirm. A new dialog box appears, indicating the operation progress. In case you want to interrupt the operation, click Cancel. Because the app detects fillets or rounds whose radius value is less than the specified value, a warning message is generated if such elements are detected.
  8. To show the fillets and rounds, select the warning message from the Warnings window.

    The fillets and rounds are displayed in red in the work area:



  9. Click Close to close the Warnings window. The operation is complete. All the edges except for edges surrounding both functional surfaces are filleted. A new feature identified as AutoFillet.XXX is added to the tree. Compared with manual filleting, using AutoFillet is also a way of considerably reducing the number of features in the specification tree.
