Comparing Models with the Quick Method

You can compare two versions (3D shape representations) of a model with the Quick method. The result is surfaces extracted from the compared models. Those surfaces correspond to the faces that form the compared models.

  1. Open the first 3D shape representation to compare (Content 1).
  2. From the Analysis section of the action bar, click Compare.
  3. Select the second 3D Shape Representation (Content 2).
  4. Edit the Distance used for the comparison.

    Under this distance, two faces or areas are considered as identical.

  5. From the Method list, select Quick.
    The comparison is carried out on the supporting surfaces.
  6. Optional: Select Embedded Content 1 or Embedded Content 2 and specify their display color.
    The embedded faces found in the selected representation are displayed in the selected color. Otherwise, they are considered as identical.
  7. Click Compute to start the comparison on all shown surfaces or solids.
    The number of faces found for each type appears in the dialog box. Those faces are displayed in the work area.
  8. Click Merge Options.
  9. Select the required check boxes:
    1. Geometrical Set to sort faces into different geometrical sets, see below for more information.
    2. Selection Set to place faces into different selection sets.
    3. Color to display faces in given colors.
    4. Full name to display the full name of the surfaces in the tree.
    5. In the Geometrical Set tab, select the type of faces to copy, and edit the names of the geometrical sets to contain them.
    6. In the Selection Set tab, select the type of faces to put in selection sets and edit the names of those selection sets.
    7. In the Color tab, select the types of faces to visualize and edit the visualization color:

    Notes:
    • The check boxes and colors that are proposed correspond to those selected in previous steps.
    • The selection of the Full name check box is optional but you must select at least one of the other three check boxes (Geometrical Set, Selection Set or Color). You can select as many check boxes as required (up to all).

  10. Select the Destination:
    • New
      • Surfaces from both compared 3D shape representations are copied in a new 3D part.
      • Surfaces are sorted in the dedicated Geometrical Sets.
    • Original
      • The surfaces from the comparison 3D shape representation are copied in the original 3D shape representation (Content 1).
      • Regarding the surfaces already present in the original model, their behavior depends on whether or not Geometrical Sets is selected or not, see below.

Identical and different surfaces are named, and extracted from the compared models, and are processed as follows:

  • Geometrical sets are created:
    • If you have selected the Geometrical Set check box, all required geometrical sets are created. This option is relevant when Destination is Original and lets you duplicate the surfaces from their original containers to the geometrical sets dedicated to the result of the comparison. Otherwise they would not be duplicated.
    • Even if you have not selected the Geometrical Set check box, geometrical sets are created: Compare creates only the geometrical sets required to contain the surfaces from the comparison model to be placed in selection sets or to be painted.
  • The selection sets dedicated to the comparison are created only when the Selection Set check box is selected, and they apply to the comparison results. If previous selection sets existed in the 3D shape representations before the comparison:
    • They are lost if Destination is New.
    • Those present in the comparison 3D shape representation are lost if Destination is set to Original, whereas those of the original 3D shape representation still exist.
  • Surfaces are painted only when the Color check box is selected.
  • As duplicate or embedded faces are ignored (considered as in NoShow), if a counterpart face is found in the other 3D shape representation, it is placed in the Different faces count, but the ignored faces are not copied to a geometrical set, or placed in a selection set, or displayed in a given color. In extreme cases, the geometrical set containing only ignored faces are not created.
