It appears that I missed the obvious solution.
I Used the Xtools solution to convert the polygon to a polyline and then
used the "Draw line to split feature" tool in AV.

Thanks to all those who responded to my question.

Yes Mike, use the geoprocessing wizard to clip the state theme with the
polygon theme you wish to use, or you can convert poly to line and back
with the x-tools ext.
------------------------
You can you can divide up a polygon by editing your theme and using the
"draw line to split polygon tool".  You can use the Convert Polygon to
PolyLine script (cvtplypl.ave) to convert a polygon to a line theme.
-------------------------
Try the shape editing function. Make the theme you want to edit active
(make sure you have a backup copy), then select the theme menu start
editing option. A button on the end of the lower button bar becomes
available (looks like a rectangle). Hold this down to access other
button choices from the drop down button list. Choose the one that is a
polygon with a line through it and is labeled "creates a line to split
polygon features". Draw a line where you want to split the polygon. Then
click on the area you want to cut and you can move it or delete it, etc.
------------------------------
I'm not sure if this is what you need...but the donutshop script will
"cookie cutter" out interior polygons from a surrounding polygon if they are
in the same theme.  it is on the scripts page of the ESRI web site.
http://gis.esri.com/arcscripts/beginsearch.cfm (Keyword: Donut gets several
tools that look useful but I've only tried donutshop). Once you draw your
sections you would apply the scipt and they become separate entities with a
hole in the state below.
---------------------
you can in AV use the slpit polygon tool and then delete the areas that you
have "Cut"
