Patrick B. McConnell over at Vector Depot continues to make our lives easier.
With this plug-in you can link to Word docs, Excel spreadsheets, websites, PDFs, and other Vectorworks drawings. Basically, you can link to any file your computer can open. All the links are organized in libraries created right in Vectorworks and quickly accessible through Bookshelf.
Bookshelf is compatible with Vectorworks versions 2008 and up and is US $20.
Thanks again Patrick for another handy-dandy plug-in!
