Delete Instances and Dimensions in Variable Pattern Feature Example (VB.NET)

This example shows how to:

  • delete instances in a variable pattern feature.
  • add and delete dimensions in the pattern table of a variable pattern feature.
'---------------------------------------------------------
' Preconditions:
' 1. Verify that the part exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens the part and selects the variable pattern feature.
' 2. Accesses the variable pattern feature.
' 3. Deletes the last and fourth instance from the pattern table
'    and pattern.
' 4. Gets the number and names of the controlling dimensions.
' 5. Selects and adds two dimensions to the pattern table and
'    deletes the second dimension from the pattern table.
' 6. Rolls forward the modified variable pattern feature.
' 7. Examine the graphics area and Immediate window.
'
' NOTE: Because the part used is elsewhere, do not save changes.
