Concrete Forming

I do alot of concrete forming using the Symons Steel-Ply system. Basically I draw a wall (usually 8" wide) in plan view. I then manually place forms around the wall. The forms are simply rectangles

2-1/2" wide and from 2" to 24" long. Is there a way to have Autocad automatically place these forms around the perimeter of the wall? For example, if I have a wall that is 10' long, I manually place 5 forms that are 2-1/2" x 24" long on each side of the wall. Most walls I deal with are much more complex than this but the concept is still the same. I am using Autocad R14. Any help is GREATLY appreciated. Thanks, CWB
