Vectorworks viewer

Vectorworks has a free viewer available for download for people who do not use the full program. Available at http://www.nemetschek.net/downloads/fundamentals/, it can be downloaded and installed on your computer. It allows you to open and view files from versions 9-12. It doesn't do conversion from vectorworks to autocad, but it will allow you to see the drawing as it was in the original program (conversion between formats sometimes causes formatting issues).
