      <p class="para_topic">The Specify As options enable you to define the vectors used to interpolate the tool axis. The required input for Add and Edit will vary depending on which Specify as option you select. You may define as many vectors as necessary to control the tool axis. You may use only one of the Specify as options in an operation to define the vectors. If you change the Specify as option after having already defined vectors, the system prompts you to Reselect before continuing. Each of the options is described below.</p>
      <div class="title_division">Vector</div>
      <p class="para_division">This option enables you to define vectors used to interpolate the tool axis by first specifying a data point on the Drive geometry (Point Subfunction) and then specifying a vector (Vector Subfunction) extending from that point. This option is dependent on the Drive geometry definition.</p>
      <p class="para_division">After you have selected OK to accept the specified vector, the system once again displays the Point Subfunction. You may continue defining data points and vectors until you select Back in the Point Subfunction. Selecting Back accepts all of the defined vectors and returns you to the Interpolated Tool Axis dialog box .</p>
      <div class="title_division">Angle/PS</div>
      <p class="para_division">This option enables you to define vectors used to interpolate the tool axis by first specifying a data point on the Drive geometry (Point Subfunction) and then specifying Lead and Tilt angles relative to the Part surface normal at the tool contact with the part surface. Lead and Tilt angles must be within the -90 to 90 degree range.</p>
      <p class="para_division">After you have selected OK to accept the desired lead and tilt, the system once again displays the Point Sub function. You may continue defining data points and vectors until you select Back in the Point Subfunction. Selecting Back accepts all of the defined vectors and returns you to the Interpolated Tool Axis dialog box.</p>
      <div class="title_division">Angle/DS</div>
      <p class="para_division">This option enables you to define vectors used to interpolate the tool axis by first specifying a data point on the Drive geometry (point sub function) and then specifying Lead and Tilt angles relative to the Drive surface normal at the tool contact with the Drive surface. Lead and Tilt angles must be within the -90 to 90 degree range.</p>
      <p class="para_division">After you have selected OK to accept the desired lead and tilt, the system once again displays the Point Sub function. You may continue defining data points and vectors until you select Back in the Point Subfunction. Selecting Back accepts all of the defined vectors and returns you to the Interpolated Tool Axis dialog box. This option can only be applied to the Surface Area Drive method.</p>
