We use the lisp routine below to add to our "support file search path".. my question is.. how do we change it so we can add to the "device driver file search path" (vl-load-com) (setq files (vla-get-files (vla-get-preferences (vlax-get-acad-object)))) (setq supppaths (strcat (vla-get-supportpath files) ";")) (setq current_directory (findfile "acad.lsp")) (setq cd_length (strlen current_directory)) (setq new_length (vl-string-position (ascii "\") current_directory nil T)) (setq current_directory (substr current_directory 1 new_length)) (setq cd_length (strlen current_directory)) (setq new_length (vl-string-position (ascii "\") current_directory nil T)) (setq acadpath (strcat (substr current_directory 1 new_length) "\")) (setq fontpath (strcat acadpath "FONTS;")) (setq palettepath (strcat acadpath "Palettes;")) (setq paths (strcat supppaths fontpath palettepath "C:\base palettes")) (vla-put-supportpath files paths)
