Allows you to create a
               keypoint line parallel to another line or curve.
         To draw a line parallel
               to a curve
            
            
               - Click the Parallel Line   icon, or choose Lines
                     > Parallel Line from the Keypoint Curve Toolbox. icon, or choose Lines
                     > Parallel Line from the Keypoint Curve Toolbox.
- Click the curve to which the new line
                  will be parallel.
                     - Guidelines are added for the curve, allowing
                        you to line up the start and/or end points of the new line.
                     
- If you click a curved line, the new line
                        is parallel to the tangent where you click.
                     
 
- Click the start point of the parallel
                  line, or type a 3D coordinate to place the point exactly.
                  As you drag the start
                     point, the Parallel Line tool displays
                     the distance between the lines in current linear units.
                   
- Click the end point of the parallel line,
                  or type a 3D coordinate to place the point exactly.
                  As you drag the end point,
                     the Parallel Line tool displays
                     the length of the line in current linear units.

               - Degree
- 
                  
                     Specifies the degree
                        of the curve. The values range from 1 to 7. The default is 1.
