To Modify Rule-based Surface Sets
* 
This topic discusses surface set modification while working inside of a tool and using the Surface Sets dialog box. If you want to modify a surface set while working outside of a tool, you can use the CTRL key to include individual surfaces in the set. You can also clear the entire surface set from the selection set. Refer to About Selection under See Also for more information about clearing a selection.
1. If you are working in a tool that uses the Menu Manager and not the dashboard, construct the surface set and open a tool. Place your pointer over a surface set label in the graphics window, right-click, and select Surface Sets on the shortcut menu. The Surface Sets dialog box opens. Skip to step 5.
2. If you are working in a dashboard tool, construct a surface set and open a tool in which to work with the surface set, or select a feature that contains an existing surface set that you want to modify, right-click, and select Edit Definition on the shortcut menu.
3. Locate the Detail collector that contains the surface set that you want to modify. Detail collectors are located on the slide-up panel. Note that you cannot use the Summary collector (located on the dialog bar) to modify a surface set.
4. Click Details. Creo Parametric pauses the tool and opens the Surface Sets dialog box. This dialog box contains a list of surface sets that were constructed using the active part, and their attributes. Notice that the surface set list contains set type and the number of surfaces contained in each set.
5. Do one of the following from the Surface Sets list:
Click Neighbor Surfaces to modify a Loop surface set. The Anchor and Loop Edge collectors appear.
Click Bounded Set to modify a Seed and Boundary surface set. The Anchor and Bounding Surfaces collectors appear if individual surfaces determine the boundary. The Anchor, Boundary loop anchor, and Boundary loop edge collectors appear if Loop surfaces determine the boundary.
Click All Solid Surfaces to modify a Solid surface set. The Anchor collector appears.
Click Quilt Surfaces to modify a Quilt surface set. The Anchor collector appears.
6. After you select a surface set from the list, the following options appear based on the surface set that you selected:
Anchor collector—Contains the anchor reference for the selected surface set. The anchor reference consists of a solid surface or quilt that belongs to the same solid part geometry or quilt.
To modify the anchor reference, click the reference to activate the collector and select a different anchor from the model. Notice that you can also use the Anchor shortcut menu command from inside the graphics window to activate this collector.
* 
You can only replace the anchor reference, you cannot remove it.
Rule—Displays the following rule-based surface set types enabling you to modify the selected surface set:
Loop surfaces—Constructs a Loop surface set by using all edges that form a loop around an anchor surface. Note that the anchor reference cannot be a quilt or an intent surface if you want to use this option.
Seed and boundary surfaces—Constructs a Seed and Boundary surface set by using all surfaces between the seed surface and the bounding surfaces, including the seed surface and excluding the bounding surfaces. Displays the Boundary options and the Include bounding surfaces check box. Note that to use Seed and boundary surfaces option, the anchor reference cannot be a quilt or an intent surface.
Surfaces of all bodies—Constructs surfaces of all bodies by using all the solid surfaces in the active part. The Reference collector appears and contains the surface reference
All solid surfaces—Constructs an All Solid surface set by using all solid surfaces in the active part. The Reference collector appears and contains the surface reference.
Boundary—Displays the type of boundary used to construct the Seed and Boundary Surface set.
Individual Surfaces—Constructs a Seed and Boundary Surface set with individual surfaces as the bounding surfaces. Activates the Bounding Surfaces collector.
Loop Surfaces—Constructs a Seed and boundary Surface set with a Loop surface set as the bounding surface. Activates the Boundary loop anchor collector.
Loop Edge collector—Contains an edge that forms a loop around a surface. This edge reference determines the neighboring surfaces for a Loop surface set. A loop edge reference consists of a two-sided edge that belongs to the anchor reference surface.
To modify a loop edge reference, click a loop edge reference to activate the collector and select a different edge from the model. This new reference replaces the existing loop edge reference. Notice that you can also use the Loop Edge shortcut menu command from inside the graphics window to activate this collector.
* 
You must select the Neighboring surfaces only rule-based surface set type to use this collector.
Consider as strong references checkbox—In seed and boundary surface sets, considers the bounding surfaces as strong references.
When set as strong references, if any of the boundary references are missing, the surface set fails, and a notification is triggered. When there is only one boundary reference, it is always considered as strong.
The default set of the check box can be set using the default_boundary_refs_strong configuration option.
Bounding Surfaces collector—Contains one or more bounding surface references that determine the boundary for the Seed and Boundary surface set. A bounding surface reference consists of a solid surface or quilt that belongs to the same solid part geometry or quilt. You can use intent surfaces as bounding surfaces.
To modify a bounding surface reference, click the reference to activate the collector and either select a different surface from the model, hold down the CTRL key and select additional references, or remove a reference. Notice that you can also use the Bounding Surfaces shortcut menu command within the graphics window to activate this collector.
* 
Surfaces removed from the Individual surface set are not considered excluded surfaces. You must select the Seed and boundary surfaces rule-based surface set type to use this collector.
Boundary loop anchor collector—Contains a surface reference that is an anchor for the Loop surface set. The Loop surface set determines the boundary for the Seed and Boundary surface set. The anchor surface reference consists of a solid surface or quilt that belongs to the same solid part geometry or quilt and acts as the anchor surface for the Loop surface set.
To modify an anchor surface reference, click inside the collector to activate it and either select a different surface reference from the model or remove the surface reference. You can remove the surface reference by clicking Clear on the shortcut menu in the graphics window or by clicking Remove on the shortcut menu that appears when you right-click in the collector. You can also use the Boundary loop anchor command on the shortcut menu within the graphics window to activate this collector.
Boundary loop edge collector—Contains an edge reference for the Loop surface set. The Loop surface set acts as a boundary for the Seed and Boundary surface set. This edge reference determines the neighboring surfaces for a Loop surface set. A loop edge reference consists of a two-sided edge that belongs to the anchor reference surface.
To modify the edge reference, click inside the collector to activate it and either select a different edge reference from the model or remove the edge reference. You can remove the edge reference by clicking Clear on the shortcut menu in the graphics window or by clicking Remove on the shortcut menu that appears when you right-click in the collector. You can also use the Boundary loop edge command on the shortcut menu within the graphics window to activate this collector.
Reference collector—Contains the surface references for the Solid surface set. Note that this reference is only displayed and can only be modified by changing the anchor reference.
Include bounding surfaces check box—Includes the bounding surfaces in a Seed and Boundary surface set.
7. Click OK. Creo Parametric saves the changes, closes the Surface Sets dialog box, and resumes the tool.
* 
You can always construct a new rule-based surface set by clicking Add and selecting the surface references from the model.
To remove a surface set from the Surface Set list, select the surface set and click Remove. Note that Individual Surfaces and Excluded Surfaces cannot be removed.
You can also remove a surface set from the graphics window by placing your pointer over the surface set label, right-click, and use Remove Set from the shortcut menu.
To clear references in the active collector, click Remove or Remove All on the shortcut menu that appears when you right-click in the collector. Alternatively, click Clear on the shortcut menu that appears when you right-click in the graphics window.
Remember that you can hold down the CTRL key and select a reference to either add an additional reference or to clear a selected reference.
To easily locate a references in the Surface Sets dialog box, place your pointer over the reference in a collector. Creo Parametric dynamically highlights the reference on the model.
Notice that as you modify a surface set in the Surface Sets dialog box, Creo Parametric dynamically displays the changes in the graphics window.
When the Surface Sets dialog box is open, you can perform Undo or Redo operations if the tool or feature supports Undo or Redo operations.
