<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><FONT size=2>The EM map I am
currently working on contains hidden buried substructures and I want to remove
these substructures from the map, leaving only the outer layer. Because the map
I am working on is very complex, I am finding it difficult to remove the buried
substructures using the Volume-eraser Tool. Consequently, I would greatly
appreciate any advice on how to remove the buried substructures, without
removing the outer layer.</FONT></P>
