# 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.
