Creating an Active Geometry by Extraction

You can create the active geometry by extracting it from the selected faces.

  1. Open the product (not a 3D part) containing the model and activate the representation containing the cavities.
  2. From the Molded Part section in the action bar, click Electrode .
  3. Select the shape that contains the geometry of the electrode cavity.

    It can be a 2D or a 3D shape.

    An axis system is created from the selected shape, and proposed as the Electrode Direction.
  4. Select the cavity faces, either by direct pick and using Ctrl Key, or using the Face selection tools.

    • Polygon Trap : Selects all the faces inside a polygon.
    • Visible in Polygon Trap : Selects all the faces inside a polygon that are visible.
    • Belt : Selects a belt of faces by propagation. You need to select the first two faces.
    • Belt up to Face : Selects a belt of faces up to a selected one. You need to select the first two faces.
    • Tangency : Select a bag of tangent faces.
    • Color : Selects a bag of adjacent faces of the same color.

  5. Select Extract Cavity Geometry in the context toolbar.
    • The selected faces turn orange.
    • If a valid contour is found, it is highlighted. Otherwise, a message is displayed to help you solve the problem.
    • Warning messages are displayed if a problem is found.
  6. Drag a valid contour to create an offset.
  7. Select Delete Geometry in the context toolbar to delete the active geometry.

    Deleting the geometry created at a given step sends you back to the previous step.

  8. Optional: Select Extrapolate Cavity in the context toolbar to create an extrapolation of the current cavity.
    1. Select an edge of the cavity.
    2. Specify the required parameters and click OK in the Extrapolate Definition dialog box.
    3. Select Validate in the context toolbar to validate the extrapolation.
    4. Define as many extrapolations as required.
    5. When available, select in the context toolbar to delete the current extrapolation.
  9. Optional: Repeat the scenarios above to create a multicavity.


    You can now add a reinforcement.
