Construct RichLine Example (VB.NET)

This example shows how to construct a RichLine.

'--------------------------------------------------------------
' Preconditions:
' 1. Create a VB.NET Windows console project.
' 2. Copy and paste this example into the VB.NET IDE.
' 3. Add a reference to:
'    install_dir\APISDK\tlb\DraftSight.Interop.dsAutomation.dll.
' 4. Start DraftSight and open a document.
' 5. Start debugging the project.
'
' Postconditions: A message box pops up when a RichLine is
' constructed in the drawing document.
