Convert dwg file to stp and igs formats

I would like to have the attached files (13 files contained in 1 zip file) converted to both stp and igs file types. These files should be able to be opened on a PC and a MAC. If for any reason I need seperate files for each OS then please provide both. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
