Title: Complicated Buffer Query

Hi folks

I am confronted with a bit of a problem and was wondering if anybody had any clues as to how I might get around it…

The situation is this:

I have a table with complex polygons that I need to buffer - only I need to maintain any existing boundaries between polygon objects - I can't have any overlaps.

Is there a way to run a complex buffer that does not buffer any line segment that is a boundary between existing polygons?

I had thought of copying my existing table, converting it to polylines and somehow removing all lines that are unique, (theoretically leaving me with only lines that are a boundary between 2 polygons) and using this table as a "cookie cutter" on the standard buffer result, but that will still leave me with loads of "slices" of polygons I will then need to delete… and I'm pretty sure there are other problems with this idea though that I don't even want to think about…

Any help would be much appreciated!

Cheers
