Desperately hoping for a WOW THAT'S SO EASY resolution for this weirdness.  

I have inherited corrupted schematic drawings.  Part of the corruption is that all the circles in my terminal and relay blocking have been broken.  What's left is hundreds of polyline segments.  I need to get them back to being circles. 

Hoping for a SO EASY solution, but any help will be much appreciated.

Sounds like a job for a custom lisp routine.  Maybe Kent Cooper will have an answer for you as he dabbles in the dark arts.  I think he may have even submitted a similar sounding lisp routine to Cadalyst back in 2011.  Not sure it would work in your situation but Kent would be able to tell you for sure.

Try the Pol2Cir utility from the Download section.

I do have such a routine on the Cadalyst CAD Tips website, at  http://cadtips.cadalyst.com/curved-objects/circle-polyline-and-polyline-circle" rel="nofollow - http://cadtips.cadalyst.com/curved-objects/circle-polyline-and-polyline-circle .
