The thickness dimension draws a small line between the inner and outer 
surfaces, two inward pointing arrows are added to the ends of the connecting 
line. To generate the arrows, use dimension twice without a connecting line. 
Text is added that 
lies along the outer surface. 

If the distance between the surfaces is large then use the inner 
dimension with outward pointing arrows.
