Create and Delete Selection Sets Example (VB.NET)
This example shows how to:
- create selection sets.
- get the Selection Sets
folder.
- get the selection sets in
the Selection Sets folder.
- get and then delete the
items in the selection sets, which deletes the selection sets.
'--------------------------------------------------------------------
' Preconditions:
' 1. Verify that the assembly to open exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens the assembly.
' 2. Creates two selection sets.
' 3. Traverses the FeatureManager design tree. If the feature is the
' Selection Sets folder, then:
' a. Gets its name.
' b. Gets each selection set in the Selection Sets folder.
' c. Gets and then deletes each selection set item in the
' selection set, which deletes the selection set.
' 4. Examine the Immediate window.
'
' NOTE: Because the assembly is used elsewhere, do not save changes.
