Create Mapping file in MAP5 to automatically translate MX MOSS layers into Autocad

Hi
Not quite sure what you are hoping to achieve here, can you give me more details on what you have and what you hope to end up with. Versions of the MX software and/or data would help too.
If you have MX in AutoCAD then this should be done for you automatically. If you just have the MX drawing then there's a piece of software called MXCHANGE that runs as an ARX app in AutoCAD that converts into DWG for you.
You might also like to try the new bentley.mx forum over on news://news.viecon.com there will be more MX realated traffic there. You can find details of FAQ's, search tools, rules and details of other groups that may be of interest at HTH
