Instantiating Power Copies
Using Part Comparison Instantiation

This command is only available with the Generative Shape Design 2 product and providing you have KT1 or PKT licenses.
This task shows how to instantiate Power Copies using Part comparison instantiation once they have been created as described in Creating Power Copies.
This instantiation mode is only available providing the Power Copy to be created is ordered and the chosen destination (that is the current feature) respects ordering rules.

Open the PowerCopyDestination2.CATPart document.

  1. Click Instantiate From Document or select Insert > Instantiate From Document... from the menu bar.

    The File Selection dialog box is displayed allowing you to navigate to the document where the Power Copy is stored.
  2. Select the document containing the Power Copy, and click Open.

    Here we selected the PowerCopyReference2.CATPart document.
    The Insert Object dialog box is displayed.

    Warning or error messages can be issued if the chosen destination is ambiguous or forbidden, for instance if you select an ordered geometrical set as the After destination.

    • In case of an error message, the destination field is emptied and the OK button is unavailable.

    • In case of a warning message, the power copy can still be instantiated but some elements may not be inserted in the chosen destination.

    Use the Reference list to choose the correct PowerCopy when several have been defined in the document.
  3. Select the Part comparison instantiation mode.

  4. Select the Destination of the instantiation.

    It is composed of two elements: a combo list corresponding to the relative position (Inside or After) and a field containing the destination feature.

    The destination depends on the current feature as it is automatically filled with the latter. If there is no current feature, the field is empty.

  5. Complete the Inputs within the dialog box by selecting the adequate element in the geometric area.

    After each selection, an indicator is displayed in the left viewer, with orientation when necessary. Click on the green arrow to reverse orientation if needed.
  6. If needed, click Use identical name to automatically select all the elements with the same name.

    This is especially useful when the input is the same one repeated several times.
  7. You can also click Parameters to display the Parameters dialog box and modify values.

    Here we increased the Radius1 value to 25 mm.
  8. Click OK to create the Power Copy instance.

    A PowerCopy Instances node is automatically created in the specification tree of the current document. The Comparison Window opens on the right side of the screen and the Scan and Synchronization toolbars are launched.
    Note that:
    • All the inputs must have been provided before launching the instantiation. Otherwise, the OK button is grayed out.
    • Instantiated features are not updated to let you update them one by one and check the consistency of the result.
    • The current feature is not yet synchronized at this step. It allows you to see the result of the Power Copy on the right side.
    • A new PowerCopy Instances node has been created in current document. This node allows the mapping between referenced objects and instantiated objects.
    When editing a feature in the Comparison Window, the edited feature is highlighted simultaneously on both left and right sides of the screen, in specification trees and 3D areas.
  9. Click First or First to update .

    The Scan command is automatically launched.
  10. Then click Next or Play update to scan the instantiated features and update them.

    Only the Structure mode is available here.
    All the inputs of TwoSurfacicHoles are valuated.
  11. Close the Comparison window.

    • Now if you launch the Quick Select command , either in the left or in the right window, the visualization is updated in both windows: pre-highlighting is synchronous and a color code indicates the current selection (green labels) in the Quick Select dialog box and the parents/children (red labels).
    • Once the Power Copy has been instantiated, you can close the comparison window and delete the Power Copy Instance features.
    The feature defined as the current object corresponds to the last instantiated component of the Power Copy.
