Construct 2D PolyLine Example (VBA)

This example shows how to construct a 2D PolyLine in a drawing document.

'--------------------------------------------------------------
' Preconditions:
' 1. Create a VBA macro in a software product in which VBA is
'    embedded.
' 2. Copy and paste this example into the Visual Basic IDE.
' 3. Add a reference to the DraftSight type library,
'    install_dir\bin\dsAutomation.dll.
' 4. Start DraftSight and open a document.
' 5. Run the macro.
'
' Postconditions: A message box pops up when a 2D PolyLine is
' constructed in the drawing document.
