Create and Modify Distance Chain Pattern Feature Example (VB.NET)

This example shows how to create and modify a distance chain pattern feature.

' Preconditions:
' 1. Verify that the assembly to open exists.
' 2. Open the Immediate window.
' Postconditions:
' 1. Opens the specified assembly.
' 2. Selects entities to create a distance chain pattern feature.
' 3. Creates the distance chain pattern feature.
' 4. After examining the graphics area and FeatureManager design
'    tree, press F5.
' 5. Modifies the distance chain pattern feature.
' 6. Examine the graphics area to verify step 5.
' 7. Examine the Immediate window.
' NOTE: Because the assembly is used elsewhere, do not save
' changes.
