      <p class="para_topic">These options determine which algorithm the system uses to interpolate the tool axis from one Drive point to the next. Select the proper option based on your requirements. </p>
      <div class="title_division">Linear</div>
      <p class="para_division">Linear interpolates the tool axis using a constant rate of change between drive points. Linear interpolates a less smooth tool axis, and provides faster performance. </p>
      <div class="title_division">Cubic Spline</div>
      <p class="para_division">Cubic Spline interpolates the tool axis using a variable rate of change between drive points. This option yields a smoother tool axis change than Linear across the defined data points. Cubic Spline interpolates a medium smooth tool axis and provides medium performance.</p>
      <div class="title_division">Smooth</div>
      <p class="para_division">Smooth provides more control on the resultant tool path axis vectors. Emphasis is given to all vectors that lie on the edges of the drive surface. This diminishes &nbsp;the influence of any interior vectors. This option is particularly useful when you need full control (based on the defined vectors) of the drive surface. Smooth interpolates a much smoother tool axis, and provides slightly slower performance. </p>
