Managing Ordered geometric Sets

You can manage ordered geometric sets within the tree.

Ordered geometric sets enable to gather various features in a same set or subset. They introduce notions of succession of steps that define the design and absorption.

This task shows you how to:

Insert an Ordered geometric Set

You can insert an ordered geometric set in the tree.

  1. In the tree, select an element as the location of the new ordered geometric set.

    This element is considered as a child of the new ordered geometric set. Inserting an Ordered geometric Set does not break the succession of steps as the order applies to all the elements of a same root ordered geometric set.

  2. From the Tools section of the action bar, click Ordered geometric Set .
    The Features box displays the elements to be contained in the new ordered geometric set.
  3. In the Name box, enter the name of the new ordered geometric set you want to insert.
  4. In the Father list, select the body where the new ordered geometric set is to be inserted.

    All destinations present in the document are listed allowing you to select one to be the father without scanning the tree. They can be:

    • ordered geometric sets
    • representations.

    By default, the destination is the father of the current object. By default, the ordered geometric set is created after the current feature.

  5. Select additional entities that are to be included in the new ordered geometric set.
    Tip: If all selected entities belong to the same ordered geometric set, the father of the new ordered geometric set is automatically set to the father of these entities.
  6. Click OK to create the ordered geometric set at the required location.
    The result is immediate. Ordered geometric Set.x is displayed, incrementing its name in relation to the pre-existing bodies, in the tree. It is created after the last current ordered geometric set and is underlined, indicating that it is the active ordered geometric set.

Important:
  • You can insert an ordered geometric set after the current feature.
  • You can insert a body into an ordered geometric set. For further information, refer to Inserting a Body into an Ordered Geometrical Set.

  • The state of a geometric set is kept in your data model.

    For instance, if the geometric set was expanded when closing the model, it is still expanded when reopening it; except if it has more than 40 children: in this case, it is automatically collapsed.

Important: You cannot create an ordered geometric set within a geometric set and vice versa.
Tip: If an element in a geometrical set is in work object then while creating a solid feature, a pad for example, a warning message appears and then the feature is inserted in the PartBody. To create the solid feature under the first valid parent body of the current geometrical set, select Insertion in Part Body if surface tool in work object check box from Me > Preferences.

Remove an Ordered geometric Set

You can remove an ordered geometric set from the tree.

Right-click the ordered geometric set and select Delete.

The ordered geometric set and all its contents are deleted.

Remove a Feature within an Ordered geometric Set

You can remove a feature within an ordered geometric set.

Right-click the feature and select Delete.
  • Deletion of a modification feature: the system reroutes the children on the element that is modified. Therefore the deleted feature is replaced by the modified feature of the upper level. In our scenario, Split.1 is deleted. As a consequence, Offset.1 now points Extrude.1.



  • Deletion of a creation feature: no reroute is possible.

Sort the Contents of an Ordered geometric Set

You may need to sort the contents of an ordered geometric set, when the geometric elements no longer appear in the logical creation order. It may be the case if you enabled the selection of drawn or future geometry.

In that case, use the Auto-sort capability to reorder the ordered geometric set contents in the tree. The ordered geometric set contains a line based on two points lines. The tree looks like this:

Right-click the Ordered geometric Set.1 from the specification and select Ordered geometric Set.1 object > AutoSort.

Instantly, the contents of the Ordered geometric Set are reorganized to show the logical creation process.

The geometry remains unchanged. Datum features are put first in the tree.

Reorder Elements within an Ordered geometric Set

The reordering capability enables you to reorder elements inside the same ordered geometric set.

Reorder a creation feature based on a modification feature

You can reorder the creation feature based on the modification feature.

The Ordered geometric Set contains a split surface (in purple) that split a filled surface by a white vertical plane, and an offset surface (in red) that is an offset of the split surface.

  1. Right-click the Ordered geometric Set.1 from the specification tree and select Ordered geometric Set.1 object > Reorder Children.
    The Reorder Children dialog box appears.
  2. Select the element to be rerouted.
    Here we chose to reorder Offset.1 (creation feature) before Split.1 (modification feature).
  3. Use the arrow to move Offset.1 up.
  4. Click OK.
    Offset.1 is now located before Split.1 in the specification tree. If you define Split.1 as the In Work Object, you can see that Offset.1 is now based on Fill.1. Split.1 was not rerouted since Offset.1 does not modify Fill.1.



Reorder a modification feature based on a modification feature

You can reorder a feature based on the modification done.

The Ordered geometric Set contains a split surface (in blue) that splits another split surface by a vertical plane. The first split surface also splits a filled surface delimited by the sketch in purple.



  1. Right-click the Ordered geometric Set.1 from the specification tree and select Ordered geometric Set.1 object > Reorder Children.
  2. Select the element to be rerouted.
  3. Use the arrow to move Split.2 up.
  4. Click OK.

Important: An error message is issued if you try to move an element toward a position that breaks the order rules.
Tips:
  • You can use the Scan command after the Reorder operation to see what moved step by step.
  • When the first element of the list is reordered upward,, it becomes the last element. Similarly, when the last element of the list is reordered downward it becomes the first element.
Note: The feature defined as the In Work Object after the Reorder operation is not affected by this operation from an update point of view:
  • When reordering upward, the feature located before the new position of the reordered feature becomes the In Work object.
  • When reordering downward, the feature before the original position of the reordered feature becomes the In Work object.

Reorder Features

The reordering capability enables you to reorder elements inside the same ordered geometric set.

  1. Right-click the geometric set from the specification tree and select the geometric Set.x object > Reorder Children.
    The Reorder Children dialog box appears.
  2. Select an element.
  3. Use the arrows to move an element up or down.

Important:
  • You cannot move an element from a geometric set to an ordered geometric set as it may break the order rules.
  • Reordering contextual features does not modify their mode: they are always set to Keep mode at creation and remain in Keep mode after being reordered.

Modify Children

You can modify the contents of an ordered geometric set by selecting its first and last component, as well as destroy it.

Important: This command is only available on sub-ordered geometric sets.

  1. Right-click the subordered geometric set from the tree and select Ordered geometric Set.x object > Modify Children.
    The Edit ordered geometric set dialog box appears with the First element and Last element boxes automatically valuated with the first and last elements of the ordered geometric set.
  2. Select the elements you want to place first and last.
    In our scenario, we chose Line.1 as the first element and Split.1 as the last element.



  3. Click OK.
    The tree is modified consequently. Elements before or after the first and last elements are rerouted in the father ordered geometric set.

    The Modify children command also allows you to remove the subordered geometric set. As a consequence, elements are rerouted in the father ordered geometric set.

Replace Features

You can replace the features within the geometric set.

This capability is only available on shape elements.

  1. Right-click the geometric set from the specification tree and choose the geometric Set.x object > Replace... command.
    The Replace dialog box appears.
  2. Select the replacing element.
  3. Click OK.

    For more information, refer to the Replacing Elements chapter in the Part Design User's Guide.

    To manage this capability, the Do replace only for elements situated after the In Work Object check box is available in Me > Preferences > Common Preferences > Object Properties > 3D Shape > Infrastructure, 3D Shape Infrastructure area, Replace section. It allows you to make the Replace option possible only for features located below the feature In Work Object and in the same branch.

Switch from Ordered geometric Set to geometric Set

While in an ordered geometric set environment, you may want to switch to a geometric set environment (for example, if you do not want to work in an ordered environment anymore).

Right-click the ordered geometric set from the tree and choose the Ordered geometric Set.1 object > Switch To geometric Set command.
The ordered geometric set feature becomes a geometric set (provided its name has been created automatically). The features after the current object that were not visualized in the ordered geometric set are put in no show in the geometric set.





Important:
  • This command is only available on a root ordered geometric set.
  • Switching from geometric set to ordered geometric set is impossible.
  • Colors may be modified.

Edit Features within an Ordered Tool (Ordered geometric Set, PartBody, or Body)

A feature can be created within an ordered tool (OGS, PartBody, Body) using different feature types (creation or modification) depending on the options selected to create it.

The options used to define a modification feature type cannot be changed when editing it, see following example with corner feature:

  1. Click Corner .
    The Corner Definition dialog box opens.
  2. In the Corner Type list, select the Corner On Support type.
  3. Clear the Corner On Vertex check box.
  4. Select two lines as Element 1 and Element 2.
  5. Select the Trim element 1 and Trim element 2 check boxes to trim and assemble the two reference elements to the corner. By selecting these options, the corner is now considered as a modification feature.


  6. Click OK to create the corner.
  7. Double-click the corner (in the tree or in the 3D geometry) to edit it.

    The Corner Definition dialog box opens.

    Both the Trim check boxes are unavailable.
