  1. Create a Representation containing a rectangular Pad.
  2. Add a constraint to one of the Pad sides.
  3. Create a formula that computes the area of the Pad.
  4. From the Compass, click 3D Modeling Apps and select Product Engineering Optimizer.
  5. Click Optimization . The optimization dialog box appears.
  6. Define the data required to run the optimization algorithm as follows:
    Optimization type: Target Value
    Optimized parameter: PartBody\Pad.1\xxxLimit\Length
    Algorithm: Gradient Algorithm Without Constraint
    Maximum number of updates : 400
    Consecutive updates without improvements: 100
    Maximum time (minutes): 5 minutes
    Update Mode
  7. Modify the target value.
  8. Select the Local Update Mode by moving the slider to the right. Click Run optimization.
    The model is updated.

  9. Double-click the optimization in the specification tree to select the Update Mode in the Optimization dialog box. Click Run optimization.
    The model is updated.
  10. Repeat this operation selecting the Global Update Mode.

Notes:

In a Representation context:

  • The Local Update Mode updates the optimized parameter, the Area in the above scenario.

  • The Global Update Mode updates the whole representation.

In a Product context with knowledge engineering specifications:

  • The Local Update Mode updates the representation.

  • The Global Update Mode updates the whole Product.
