Creates a circle based on a center point and a radius or diameter value.

Radius

Enter a value, or specify a point.

For example:

Diameter

Enter a value, or specify a second point.

For example:

3P (Three Points)

Creates a circle based on three points on the circumference.

For example:

Tan, Tan, Tan

Creates a circle tangent to three objects.

For example:

2P (Two Points)

Creates a circle based on two endpoints of the diameter.

For example:

TTR (Tangent, Tangent, Radius)

Creates a circle with a specified radius and tangent to two objects.

Sometimes more than one circle matches the specified criteria. The program draws the circle of the specified radius whose tangent points are closest to the selected points.
