<h1>Insert Block Instance Example (VB.NET)</h1>
<p>This example shows how to insert a Block instance in a drawing document.</p>
<pre>'--------------------------------------------------------------
'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:
'    <i>install_dir</i>\<b>APISDK\tlb\DraftSight.Interop.dsAutomation.dll</b>.
' 4. Start DraftSight and open a new document.
' 5. If C:\<b>Block.dwg</b> exists, then skip this step.
'    - or -
'    If C:\<b>Block.dwg</b> does not exist, then construct
'    some geometry in the drawing, save the drawing
'    as C:\<b>Block.dwg</b>, and open a new drawing document.
' 6. Start debugging the project.
'
' Postconditions: A message box pops up when a Block instance is
' inserted in the drawing document.
