Place Arc

Use it!

Used to place a circular arc. Arcs can be placed clockwise or counterclockwise.

Tool SettingEffect
Method

Two options for Method:

  • Center
    • — position by an endpoint, the center, and a point that defines the sweep angle.
  • Edge
    • — position by three points on the arc edge.
Radius

If on, sets the radius.

Length

If on, sets the length of the arc.

Start Angle

If on, sets the angle between an imaginary line between the center and the arc's beginning and the view's x-axis.

Sweep Angle

If on, sets the arc's sweep angle.

To place an arc by its center
  1. Select the Place Arc tool.

  2. Set Method to Center.

  3. Enter a data point to define the arc's beginning, from which the arc extends.
    or
    If Radius, Start Angle, and Sweep Angle are all on, enter a data point to define the arc's center and place the arc.

  4. If necessary, enter a data point.
    If Radius and Start Angle are on, this data point defines the arc's sweep angle and places the arc.
    If Sweep Angle is on, this data point defines the arc's center and places the arc.
    Otherwise, this data point defines the arc's center.

  5. If necessary, enter a data point to define the arc's sweep angle and place the arc.

    Place Arc, with Method set to Center. Left: All constraints off. Right: All constraints on. Radius, denoted by “R.” Start Angle, denoted by “ST.” Sweep Angle, denoted by “SW.”

      

    Arcs (with Method set to Center) can be placed either counterclockwise (left) or clockwise (right).

      

To place an arc defined by three points
  1. Select the Place Arc tool.

  2. Set Method to Edge.

  3. Enter a data point to define the arc's beginning.
    If Radius, Start Angle, and Sweep Angle are all on, the arc is placed.

  4. If necessary, enter a second data point to define a point on the arc.

  5. If necessary, enter a third data point to define the endpoint and sweep angle.

    Place Arc, with Method set to Edge. Left: All constraints off. Right: All constraints on. Radius, denoted by “R.” Start Angle, denoted by “ST.” Sweep Angle, denoted by “SW.”
