|Shift+A||Alt+C, A||Vector ->Arc (Center/Begin/End)|
This Arc command draws an arc based on three points set by the user.
Activate the Arc (Center/Begin/End) command. Set a point for the center of the arc, a second point that indicates the arc’s radius and starting angle, and a third point to indicate the clockwise span angle. The tool remains active and awaiting points for another arc. This command always draws the arc counter-clockwise from the second point.
Use the Esc key to erase the previous point in the arc currently being created. If no points are set, Esc ends the Arc command.
Use Gravity to snap to the existing point in the vector data that is closest to the cursor’s position. Gravity may be activated in two ways – press the Period (.) key, or right-click to activate the Context menu and choose Gravity. If selected from the context menu, right-click will continue to function as Gravity until a new tool is selected.
