Seed File: atfplan_only

We have drawings in BA 2004 that use the atfplan_only seed file. in BA 2004, we have use of the walls, doors and windows using this seed file. When using BA V8i, i get an error which tells me that "Preserve 3D data must be selected in the Extraction Definition". In the drawing manager under the output tab, Preserve 3d data is selected and i cannot use the walls, doors or windows. Is there another place i should be looking?
