i posted this in Visual Lisp but did not get a response. we changed pc3 names (for better organization) so all our drawings have to be changed. if i do not find a way to do this automatically, i will have a hard time convincing my users. is there a routine to substitute an old pc3 name with a new one? each drawing have multiple layouts and/or saved page setups. plotter.pc3 to AB plotter.pc3 printer.pc3 to AB printer.pc3 etc i know very little of lisp. can somebody help? thanks
