Creating an AutoCAD polyline from an exploded region

Hello,
How can we find all closed boundaries from all lines in the drawing. CreateFromCurves doesn't work if all of the selected curves to do not form a closed region and sometimes create more than needed. In the attached picture is a very simple example of air ducts drawn with lines. I want to convert them to closed polylines and find 2 closed ones in the picture below not 3 (the outermost big duct).
Thanks,

I have not tried it now, but didn't you get two regions from this picture?

Hello,
I get 2 regions from this picture, 2 desperate and 1 the outer most.
In a complex drawing there will be lots of unwanted regions.
Thanks,
