Brian:
This is a problem that often has to be picked apart item by item.  It usuually has to do with blocks.  Often blocks are made with their nested objects residing on layers that shouldn't even be a layer in a drawing.  Sometimes there are even blocks within blocks that should be exploded and have all their objects on layer "0".  It's especially difficult to automatically find all that stuff in AutoCAD LT because LT doesn't have support for LISP.  So more things have to be done manually, unfortunately.  Many people who have AutoCAD LT also purchase Toolkits for LT from www.drcauto.com.  Some of kits supply support for AutoLISP/Visual LISP and VBA.  I highly recommend drcauto.com for all those who have AutoCAD LT.  There are other applications out there such as SUPERPURGE at
