Create Multi-row Callouts Example (VBA)

This example shows how to create  multi-row callouts.

' Preconditions:
' 1. Copy and paste this code in the main module.
' 2. Click Insert > Class module and copy and paste
'    this code in the class module.
' 3. Click Tools > References > SOLIDWORKS version
'    exposed type libraries for add-in use.
' 4. Open a part or a fully resolved assembly.
' 5. Select one or more geometric entities in
'    the graphics area.
' Postconditions: Observe the graphics area while stepping
'    through the macro (put your cursor in the main module
'    in the IDE and press F8 repeatedly) to verify that callouts
'    are attached to each geometric entity selected in
'    Preconditions step 5.
' NOTE: Selecting features in FeatureManager design tree is
' not currently supported.
