You can export a plot in three different formats: DXF (Drawing Exchange Format, for CAD programs), EPS (Encapsulated PostScript, for Adobe Illustrator and other illustration programs), and PICT (the native Macintosh graphics format).
To export a plot, select "Export" under the File menu, and choose the desired format from the submenu.
The plot will be exported just as you see it in the main window, and the plotting options you currently have selected will be respected: if the chord line is turned on, it will be exported, and so on. Note that in DXF and EPS formats, text is NOT included.
