Creating a Surface Extension Manager

You can create a Surface Extension Manager feature to provide a simple and effectife way to compute extensions.

Before you begin: See About the Extension Process.
  1. From the Die Face section in the action bar, click Surface Extension Manager .
  2. Select an Analysis Boundary.

    It contains all the information to compute extensions (Axis, surfaces, boundaries, planes, …).

    Tips:
    • You can modify the type of the Analysis Boundary to have extensions or other solutions.
    • You can ignore some results.
    • You can impose a solution on a boundary for the Fill Complex Gaps option instead of a global solution type.
    • If you pick a Surface Extension, the planes are displayed for local modification.

  3. Select a global splitting element, such as a Convex Polygon.
  4. Enter the values of Minimum G2 Length and Minimum G1 Length.

    Extensions are computed in auto-pilot mode with a minimum length.

  5. Under Parameters, select relevant check boxes.
    • Verify Tangency.
    • Verify Overlapping.
    • Verify Curvature.

      Enter the Curvature Threshold value beyond which the extension is rejected.

  6. Click Apply.
    Surface Extension Manager computes Connect Surfaces or Fillet Connects where the quality is guaranteed, for example on a Transition Boundary.

    Because the boundary is divided in several Surface Extension Boundaries, gaps need to be filled to create a complete surface belt.

  7. To fill remaining gaps, select the Fill Complex Gaps check box and select an option from the list.
    • Connect Surface
    • Fillet Connect

A Surface Extension Manager feature is created in the tree. It contains

  • The Minimum Length and Curvature Threshold parameters
  • Surface Extension Results and Connect Surface Results or Fillet Connect Results, that each contains a result surface.

You can edit each feature in Surface Extension Manager. Editions are taken into account in the final join created by Surface Extension Manager.
