<h1>Insert Splines Example (C#)</h1>
<p>This example shows how to:</p>
<ul>
<li><font face="Verdana" style="font-size: 8pt">construct several Splines, which are displayed as
the Dassault Systèmes logo in a DraftSight drawing. </font></li>
<li><font face="Verdana" style="font-size: 8pt">fire events before
and after commands are executed.</font></li>
<li><font face="Verdana" style="font-size: 8pt">select a group of entities
and modify a member in that group of entities.</font></li>
<li><font face="Verdana" style="font-size: 8pt">execute a command using
IApplication::RunCommand.</font></li>
</ul>
