      <div class="title_division"> Vector Only</div>
      <p class="para_division">Vector Only allows you to specify an engage/retract move in terms of a vector and a distance. The vector establishes the direction of the engage motion, and the distance value determines the length. Choose one of the available methods of defining a vector shown above. The defined vector displays on the graphics screen at a location appropriate to the option chosen.</p>
      <p class="para_division">Enter a value representing the length of the engage motion. A positive distance value causes the direction of the engage move to be the same as the direction of the vector. A negative distance value causes the direction of the engage move to be opposite to the direction of the vector.</p>
      <p class="para_division">When you generate the tool path, the tool moves the specified distance and direction along the engage vector to the first point to be machined.</p>
