Scanning a 3D Shape and Defining In Work Objects

You can scan a 3D shape and define an object as current without taking the complete 3D shape into account. It can be useful for analyses or a better understanding of the design.

Both geometrical sets and ordered geometrical sets can be scanned.

Before you begin: Create a 3D shape containing geometric elements.

Creating Datum Elements
  1. From the Review section of the action bar, click Scan or Define In Work Object .
    The Scan dialog box appears.
  2. Select the scan mode.
    • Structure: All features of the 3D shape are scanned in the order of their display in the tree.
      Important: Internal elements of sketches, part bodies and bodies, ordered geometrical sets, and elements belonging to a geometrical set are not taken into account by this mode.
    • Update: All features of the 3D shape are scanned in the order of the update which is not necessarily the order of the tree.
      Important: This mode is unavailable with Power Copies.
  3. Click Display Tree .
    The Scan Tree dialog box containing a tree of features appears.
    • For the Structure mode, all features belonging to the geometrical feature set are displayed. The current position in the scan tree corresponds to the in work object.
    • For the Update mode, all features belonging to the 3D shape are displayed. The current position in the scan tree does not correspond to the in work object. The underlined object in the scan tree is not necessarily the one underlined in the tree.
      Notes:
      • Datum features appear first in the scan tree. Geometrical sets and ordered geometrical sets do not appear. Deactivated features appear.
      • The 3D shape is put in No Show mode to build a new 3D display containing the same features but in a different order. As a consequence, if a geometrical set or an ordered geometrical set is in No Show mode, it is ignored and its elements are considered as being in Show mode. To put the contents of this geometrical set or ordered geometrical set in No Show mode, use the Geometrical_Set.x object > Hide Components contextual command.
  4. Select a feature in the scan tree or in the tree.
    The feature is highlighted in the tree and the work area and made current.
  5. Click Previous .
    You move to the previous feature.
    Note: Datum and deactivated features are not scanned.
  6. Click First .
    You move to the first feature.
    Note: In case there are several datum features, the last one is highlighted as they are all scanned at the same time.
  7. Click Next .
    You move to the next feature.
    Note: Datum and deactivated features are not scanned.
  8. Click Last .
    You move to the last feature.
    Tip: Moving to the next or last feature enables you to update elements that are not up-to-date.
  9. Click First to Update .
    You move to the first element to be updated and consequently update it.
  10. Click this icon repeatedly.
    You find the next element to be updated and so on until an information panel appears to inform you that both geometry and 3D shape are up-to-date.
  11. Click Play Update .
    The update of the geometry is replayed.
  12. Exit the command.
    The current object is highlighted in the work area and the tree. If the object was in No Show mode, it is put in Show mode as long as it stays current.

Notes:
  • Defining a feature as current without scanning the whole 3D shape is possible using the Define in Work Object contextual command of the tree. The feature is put in Show mode if needed, and keeps its status even if another feature is defined as the in work object.
  • When clicking a sub-element in the 3D shape, it is in fact the feature used to generate this sub-element which is selected as the in work object. Likewise, this feature is edited when double-clicking a sub-element.
  • When a collapsed contextual element is highlighted, it is the node of its set that is highlighted in the scan tree.
  • To display 3D parameters attached to Part Design features, select the Parameters of features and constraints check box under Me > Preferences > 3D EXPERIENCE Platform Common... > Display > 3D Shape Infrastructure > Display in geometry area.
