Filling Holes on Surfaces

You can fill holes on surfaces. Design changes are supported.

  1. From the Die Face section of the action bar, click Shut Off Surface .
  2. Select a surface.
  3. Select an axis system (Pulling or stamping direction).

    Selecting an axis system is mandatory to compute draft patches, optional otherwise.

    Note: Draft Patches are an option to fill complicated holes. However, huge discontinuities in the wire that defines the hole can lead to a twisted result.

  4. Hover over Automatic fill ratio.
    The percentage of filled holes is displayed.
  5. Click this display to access filled holes and the corresponding solution.
    • Each category is displayed in an editable color, to help you make decisions.
    • Expand a category to see the whole list.
    • Optional: Select one line, either in the list or in the 3D area, and choose an action from the context toolbar.
  6. Expand More for further actions.
    1. Expand Quality checkers and select the required ones.

      • Connect Checker to analyze tangency between faces.
      • Isophote Mapping to display discontinuities between faces.
      • Manual Fill Analysis to verify that continuity requests are met for holes filled by a user action.
        Note: User actions can be:
        • Remove the filling.
        • G0, G1, or G2 Fill.
        • Piece-Wise Fill (With G0, G1, or G2 constraints and G0, G1, G2 Connect Curve).
        • Fill by Draft Patch, with parameters proposed in context toolbar.

    2. Set Continuity Tolerances .
    3. Define G0, G1 or G2 continuity on automatic fills.

      Note: A Piece-Wise fill with a G2 continuity may fail when processing two bounded faces supported by trimmed surfaces with a large empty area.

    4. Optional: Decide to join the initial surface to the result fillings.
    5. Opt to Fill complex holes.

      This option provides more results but requires that you verify them as quality is not guaranteed.

  7. If you have selected Fill complex holes, expand Advanced.
    1. Select one hole in the list to inspect it.
    2. Set required parameters.

      Hover over a parameter for more information.
