      <p class="para_topic">The standard insert type covers the threading types Standard and Buttress from Unigraphics up to V15. This type allows for the specification of threading tools with symmetric or asymmetric V-profile (e.g. NPT or V-profile), as well as profiles with a radius (e.g. Whitworth or API rounded).</p>
      <p class="para_topic">The ACME threading tools as available in Unigraphics up to V15 can now be specified using the trapezoidal insert type.</p>
      <p class="para_topic">The tracking point is the point of the tool which is output to the tool path. See <a class="links" href="javascript:void(0)" onclick="top.openFile('mfgturning/turn_tool_track_def_ov.html');return(false);">Define Tracking</a> for more information.
