I have added this to my acaddoc.lsp to run the layerfilterdelete command: (load "s:\_AutoCad 2005 Settings\Lisp\removelayerfilter.lsp") (c:lfd) (princ) But, How do I tell it to ENTER thru the following question: "Wildcard mask for filters to keep, or <Enter> to delete all": or, I thought I could have a duplicate removelayerfilter.lsp that is edited to not ask and delette all filters but I don't know enough about lisp to edit it. Thanks, Chris
