Creating Corner Fillets

You can create corner fillet surfaces between sets of surfaces and curves used as support elements.

This task shows you how to:

Before you begin:
  • You must have access to the ICEM Shape Morphing app.
  • Open a 3D shape containing three intersecting surfaces and an additional surface which can be used as support.
Important:
  • For Ball corner type, you need three intersecting fillet surfaces
    • which must be created with the Advanced Fillet command, and
    • which must have equal radii.

    Therefore, selection is limited to appropriate geometry.

  • For Blend corner type, you need three intersecting fillet surfaces and a support surface. The intersecting fillet surfaces
    • can be created by any fillet surface creation command,
    • can have unequal radii.

Creating a Ball Corner

Before you begin: Open a 3D shape containing three intersecting fillet surfaces with equal radii.
  1. From the Surface section of the action bar, click Corner Fillet .
  2. From the Corner Type box, select Ball.

    With this corner type, a ball with the specified value is positioned in the corner. The connecting surfaces between ball and fillets form the ball corner, thus ensuring that the minimum radius is directly applied on the ball surface.

    For this corner type must be selected as input elements three fillet surfaces created with the Advanced Fillet command. No other input type is accepted as valid input, i. e. Styling Fillet or Tri-tangent Fillet features.

    If the corner type Ball is selected, the input boxes Fillet 1 to Fillet 3 are displayed. For each box only one existing Advanced Fillet feature can be selected.

    The Support option is not available.

  3. Select three fillet surfaces.
  4. Select the Continuity and specify a Ball Radius.
  5. Click Apply.
  6. Select the Trim Fillet options to trim the fillet surfaces at the created ball corner.
  7. Click OK.

Note: As for the corner type Ball, the input is more restrictive as for the corner type Blend, all unusable input elements are removed from the selection when switching from Blend to Ball. A warning dialog box is displayed where you can choose between
  • Yes, to switch to the corner type Ball and loose all unusable inputs, or
  • No, to stay in the current mode and preserve all inputs.
The selection removed when switching to the corner type Ball will not be restored when switching back to Blend.

Creating a Blend Corner

Before you begin: Open a 3D shape containing three intersecting fillet surfaces with unequal radii.
  1. From the Surface section of the action bar, click Corner Fillet .
  2. From the Corner Type box, select Blend.

    The corner fillet consists of four edges. Three of them are the trimmed fillets and the fourth edge is connected to a support surface.

    For this corner type, three fillet surfaces of any type can be selected as input elements.

    If the corner type Blend is selected, the input boxes Surface 1 to Surface 3 are displayed. You can select only one surface for each input box.

    The Support option is available for the selection of one or several support surfaces.

  3. Select the three fillet surfaces and the support.
  4. Specify a value for Length 1 and Length 2.
  5. Click Apply.
  6. Select the Trim Fillet options to trim the fillet surfaces at the created blend corner.
  7. Click OK.
