You can define selective instances to produce different arrangements of components within a shared assembly. As a result, Creo Elements/Direct Annotation views of the assembly will be different depending on the context of the view set; that is, they depend on the assembly instance that is the master of the view set.
View sets are attached to the contents information of their owners. Since shared assemblies all derive from unique contents data, specific instance information created by selective unsharing within the shared assembly structure implies that views of the assembly shares will vary. The actual view geometry that is calculated depends on the context in which the view set is placed.
When you have a view set of an assembly that contains selective instances, you can choose the assembly context used by the view set. Although the basic geometric contents information is the same in all contexts, selective instance information affects the relative positions of assembly components as seen in views of the assembly. For this reason, the view set master is needed to specify which assembly share is to be used when computing view geometry.
To set the selective instance master for a view set,
1. Click Structure and then, in the Part & Assy group, click Selective.
2. Click Sel Master 2D. The Sel Master 2D dialog box opens.
3. Specify the View Set for which you want to set the selective instance.
4. Click New to open the View Set Master 2D table.
5. Select a master from the table by double-clicking an entry or by highlighting an entry and clicking Apply.
6. Click to complete the operation.
Creo Elements/Direct Annotation uses the specified view set master to derive view geometry.
The view set master applies to subsequently created views (including dependent views), but it also affects the update of views created with a different master of the same view set.
