Hello,
I am new to the board and thankful for it!
 
I am tring to figure out how CAD can help me interpolate contours?  I have both AutoCAD  2008 and 3D Civil.  In my drawing, I have existing 3 feet contours, but I need 1 foot contours.  Is there a way CAD can interpolate those 1 foot contours for me?  Thanks!!
