CIRCLE Command

Creates a circle

Draw toolbar:
Draw menu: Circle
Command line: circle

3P / TTR / <Center point>: Enter an option or specify a point


You can create a circle by beginning with the center point or one of three points on the circumference, or you can select objects to which the circle is tangent.

3P

Draws a circle based on three points on the circumference.

First point: Specify a point (1) or enter a value
Second point: Specify a point (2) or enter a value
Third point: Specify a point (3) or enter a value

TTR (Tangent, Tangent, Radius)

Draws a circle with a specified radius that is tangent to two objects.

Enter Tangent spec: Select the first object
Enter second Tangent spec: Select the second object
Radius <current>: Specify a distance or press ENTER

Sometimes more than one circle matches the criteria specified. AutoCAD LT draws the circle of the specified radius whose tangent points are closest to the object selection points, as shown below.

Center Point

Draws a circle based on a center point and a diameter or a radius.

Diameter / <Radius> <current>: Specify a point, enter a value, enter d, or press ENTER

Radius

Defines the circle's radius. Enter a value or specify a point (2). The distance between this point and the center point determines the radius of the circle.

Diameter

Draws a circle using the center point and a specified distance for the diameter.

Diameter <current>: Specify a point (1), enter a value, or press ENTER
