# Arcs

An arc is a curved line contained on the circumference of a circle. Arcs are composed by a center point, a starting point and an ending point, and are drawn counter clock-wise from the starting point to the ending point. To draw an arc, first press the arc button on the mode palette. Point to where you want the center point of the arc to go, and drag the mouse. Release the mouse over where you want the starting point of the arc to go. Drag the mouse to where you want the arc to end and release to return to select mode.

Use the style palette to define dash style and line width. There are eight dash styles and six line widths to choose from.
