Hi,
   I've been asked at my job to take a stormwater Management drawing and use the contours to create several trap lows at certain specific elevations and tell the designer the areas for each one.
 
   I've imported the drawing and it's surfaces into Civil 3d.  However, so far I can't find a way to use Civil3d to automatically calculate these trap lows and draw them for me.  Has anyone done this?
