DWF Composer 2 now has custom Symbols. Custom symbols or stamps some call it allow you to generate a library of markup symbols to place in your drawings. The symbols can be created a couple different ways. You can simply print a DWF from AutoCAD 2006 using the Block Template then import those blocks into your DWF Composer as a Custom Markup catalog.
Another way to import these symbols is simply create a object and print it to DWF using the DWF6 eplot.pc3 setting than import that DWF into DWF Composer 2 using the Import each sheet a symbol.
