      <hr noshade="true">
      <p class="para_topic">The purpose of this case study is to illustrate how helper geometry (typically created with Modeling features) can be leveraged to trim sparking heads to specific geometric targets.  In this case, the sparking head will be trimmed to the top-most edge of top-most fillet on the workpiece.    </p>
      <p class="para_topic">Please note that this case study requires a modeling license for the purpose of using Extrude and Trim Body. </p>
