Creating Automatic Fillets

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

Auto Fillet is available depending on the license.

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

About Automatic Fillets
  1. From the Refine section of the action bar, click Auto Fillet .

    The Automatic Fillet.x dialog box appears.

    Tip: Optionally, click More to expand the dialog box and display images helping you define your specifications.
  2. In the Selection type box, select one of the following computation modes.

    • Current solid: the whole current solid is filleted. This is the default mode.
    • Faces selection: the edges around the faces selected are filleted.

    Help images reflect the computation mode you select.

  3. In the Functional faces box, select the faces you do not want to fillet. . The selected faces turn purple, indicating that they will not be filleted.


  4. In the Fillet radius and Round radius boxes, enter a radius value for all edges requiring filleting or rounding (convex or otherwise).
    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.
  5. 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 is disabled. This means that if you modify the radius value, the round value is automatically modified and displays the same value as the radius value. Select this option to apply a radius value. If this option is disabled, its value is half the smallest value. For example, if the fillet radius value is 5 and the round corner value is 4, then the value used is 2.

  6. Select Show curvature less than check box to ensure that the app displays the fillets and rounds whose radius value is less than the smaller radius value you entered.
  7. Click OK to confirm.
    A new dialog box appears, indicating the operation progress.
  8. In case you want to interrupt the operation, click Cancel.
  9. If the app detects fillets or rounds whose radius value is less than radius value, a warning message is issued.
  10. To show the fillets and rounds, select the warning message from the Warningswindow.

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



  11. Click Close to close the Warnings box.
    The operation is complete. All the edges except for edges surrounding both functional surfaces are filleted. A new feature identified as AutoFillet.x is added to the tree. Compared to manual filleting, using AutoFillet reduces the number of features in the tree.
