In theory, this sounds like it would work fine using BCL -- but -- you should test it out and see if it actually would work that way. We'd be all interested in hearing of your results.
I don't have a clear picture in my head of what your circles and lines would look like in your CAD drawing, but when you create them, if you could post the .dxf file here, I'd like to see what they looks like.
