Menu: Draw / Arc
Most of the Arc tools are identical to Circle and Ellipse tools. After the initial circle is created, the arc is cut from it by defining the start and end angles.
You can display the Arc toolbar by right-clicking in any
toolbar area and selecting Arc. 
Arc tools are available on the Draw toolbar, which is located by default along the left side of the window. 
Start and end angles can be changed with the Edit Tool (node editing). See "Changing Start and End Angles" on page 264.
