Hi folks, If anyone wishes to use my symbols and line styles in their diagramming click here; http://www.itsjustabitofpaper.com/Pages/Pages/Blog%20Posts/Blog007Symbols.html
Download the version that will work for your particular version of Illustrator and save it in your Pre-sets folder. They won't show up in the Symbols and Graphic Styles libraries until you restart Illustrator. And I'll be pleased to see any of you who are coming, at Edinburgh.
