Generating an Extraction

After designing the cardboard package, you can generate an extraction. The simulation preparation functionality automates the generation of an abstraction model of the package to be used in the simulation.

  1. From the Model section of the action bar, click Extraction .
  2. Define the extraction mode:
    OptionDescription
    Remove fold Removes the fold faces.
    Preserve fold Preserves the fold faces of the cardboard package. Fold cuttings are represented by the fold face in the cardboard package.
    Preserve fold and display parameters Preserves the fold face of the cardboard package and displays the specification parameters in the extraction results.

    Note: The Preserve fold or Preserve fold and display parameters mode preserves faces only for the fold cutouts that are created with the Keep Cycle mode set to True.

  3. Select the solid body to extract.
  4. If the 3D shape is folded, select a reference face.
  5. Optional: To hide the body, click Hide/Show body to extract .

The Extraction Set node contains all the features generated during the simulation preparation.

  • The Surface Set node contains the Mid Surface Extract feature, that is a shell surface.
  • The Output Set node for the Remove fold mode contains the final cardboard topology:
    • Output panel faces corresponding to the number of panels in the solid package.
    • Two output folds per fold face.
    • An axis system per fold and panel face. The x axis is oriented along the fold axis.
  • The Output Set node for the Preserve fold and Preserve fold and display parameters modes contains the final cardboard topology:
    • An output panel for every panel face.
    • An output fold for every fold face.
    • An axis system for every panel face and fold face.
  • The Output Group Set node contains the same features as in the Output Set. It gives a logical grouping in the tree and lets you create simulation features. It is only available with the Remove fold mode.


Warning: If the extraction set has already been generated in the current view, no set is generated. However, if you switch to another view, a new extraction set is generated.
