I know I should upgrade, but money is tight. In the meantime, is there a way for my clients to save their files, which are created in SW 2004, in a Solidworks format that can be opened by my old 2001 plus SW? Or, is saving them in IGES format the only choice? IGES will give me a read-only file, right? Thanks for any help. Dick dick at antiochsys.com
