Preferably, running this macro would do this:Check to see if drawing is open if not, then return message box to user: "only works on drawings"Open up save dialogue box with file type defaulted to PDFAllow user to choose folder location to save to. Store the user's filename and folder location to variablesOpen up main models referred to by model (highest level models in BOM tree)Automatically save each model in Step format and in IGES format with the same name as the drawing and in the same folder location.End ProgramAlternatively, rather than opening up the save dialog box, the macro can ask the user to supply any wanted suffix to the filename (such as the revision number or the date) and then ask the user for the folder location.If this macro is possible it would be great and could save me a ton of time!Cheers,R
