The templates set up useful classes for various types of drawings. This is helpful because the classes can be quite complex, as they should be to be effective. The name automatically sets up a menu selection where the Arch menu leads to the Wall menu and then to Ext. Sheets are basically plot views that you can view on-screen or output to a printer or plotter. They combine the layers you make visible and the classes on those layers that you can print.
Sheets make it easy to prepare plots and very easy to do on-screen presentations for clients.
The document referencing system is particularly well-tuned for sharing documents that create workgroup standards for specific classes such as doors, windows, hatches, and data tables. In VectorWorks, the system moves a copy of the referenced documents into the file structure of the drawing you are working on. This can also make for big files, but they seem to load fairly fast anyway, and disk space is getting cheaper all the time. VectorWorks includes drawing managment tools that track changes to your master documents. Drawing tools VectorWorks has all the basic 2D drawing tools you need.
