  2. In AutoCAD , arcs can be constructed using any three of the following characteristics of an arc – its Start point; a point on the arc ( Second point); its Center ; its End ; its Radius ; the Length of the arc; the Direction in which the arc is to be constructed; the Angle between lines of the arc. These characteristics are shown in the menu appearing with a click on the Arc tool in the Home/Draw panel

  3. To call the Arc tool click on its tool icon in the Home/Draw panel, click on Arc in the Draw toolbar, click on Arc in the Draw drop-down menu, or enter a or arc at the command line. In the following examples initials of command prompts will be shown instead of selection from the menu shown bellow:

  4. First example ・Arc tool • Left-click the Arc tool icon. The command line shows: • Command: _arc Specify start point of arc or • [Center]: 100,220 • Specify second point of arc or [Center/End]: 55,250 • Specify end point of arc: 10,220 • Command:

  5. Second example ・Arc tool • Command: right-click brings back the Arc sequence • ARC Specify start point of arc or [Center]: c (Center) • Specify center point of arc: 200,190 • Specify start point of arc: 260,215 • Specify end point of arc or [Angle/chord Length]: • 140,215 • Command:

  6. Third example ・Arc tool • Command: right-click brings back the Arc sequence • ARC Specify start point of arc or [Center]: 420,210 • Specify second point of arc or [Center/End]: e (End) • Specify end point of arc: 320,210 • Specify center point of arc or [Angle/Direction/ • Radius]: r (Radius) • Specify radius of arc: 75 • Command:
