4. Click Extract.
   The result depends on the order of selection. If the shorter of two lines is selected first, the midline is generated with a length similar to the shorter line. In addition, the midline is created only between the first line sgement and a protion of the second line segment.
   If the longer line segment is selected first, the length of the midline is an average of the two line lengths.
   A new midline is created and drawn between the two selected lines.
