Under the type tool there is the line tool it is a pull out menu the next too is the arc tool.
Thanks for the Help.
Can i suggest that you explore al the tools there are drop down menus and on the panels as well in the upper right hand corner there is a drop down with useful functions and options. Also look at the control panel under the menu bar as you change tools to see the option each tool has and also some tools have further settings if you double click the icon in the tool bar other have option if you click in the document window once you have selected them.
But the best advice I can give you is to buy Mordy Goldings book Real World Illustrator CS 4 he also has one for the suites, it is a worthwhile investment.
