Matching Surfaces

You can match between several objects and boundaries, for example surface-surface match or curve-surface match.

Recommendation: For commands creating transitions between surfaces, use a minimum order of 6 to obtain optimal results.

Before you begin: Create a 3D Shape containing topologically non-contiguous surfaces or curves.

  1. To display control points, do the following:
    1. Select the surfaces to be matched.
    2. Press Alt, left-click and click Controls in the mouse menu.
    3. Click in the work area to clear the selection.
      The control points are displayed on the previously selected surfaces. The subobject selection mode is still active.
    4. Press Strg + Alt, left-click, and click object selection mode in the mouse menu.


  2. Select first the connecting edge of the surface to be connected (target) and then the adjacent edge of the reference surface (source).
  3. From the Surfacing section of the action bar, click OmniMatch .


    The matching is created with the default parameters G2 Continuity and Mapping type Exact.

    An OmniPlane displays the main direction into which the target control points are moved. You can modify the direction using the Direction options or manipulating the handle.

  4. To change the continuity, do one of the following:
    • In the OmniMatch panel, move the Continuity slider.
    • In the work area, move the pointer to the connected edges, press Alt, right-click, and select another continuity in the mouse menu.
  5. Press Strg + Alt, left-click, and click subobject selection mode in the mouse menu.
  6. Modify the source geometry.
    The target geometry is adapted in a way to keep the selected continuity.

  7. In the OmniMatch panel, change the Direction, for example from Z to X as shown in the example.
    The target control points are only moved in x-direction and fixed in the yz-plane. The control points distribution changes and provides an improved result quality.

  8. Click OK.
    A Matching.Condition.n feature is added to the tree, except if Datum is selected in the Soft Parametrics section.
