<h1>Insert Block Instance Example (VBA)</h1>

<p>This example shows how to insert a Block instance in a drawing.</p>
<pre>'--------------------------------------------------------------
' 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,
'    <i>install_dir</i>\<b>bin\dsAutomation.dll</b>.
' 4. Start DraftSight and open a new drawing document.
' 5. If <b>C:\Block.dwg</b> exists, then skip this step.
'    - or -
'    If <b>C:\Block.dwg</b> does not exist, then construct
'    some geometry in the drawing, save the drawing
'    as <b>C:\Block.dwg</b>, and open a new drawing document.  
' 6. Run the macro.
'
' Postconditions: A message box pops up when a Block instance is
' inserted in the drawing document.
