The Circle command draws a circle from a center location and a radius.

Steps

Pick the center location.
Pick a radius location or specify an option.

Command-line options
Deformable	Draws a NURBS approximation of the curve will be created with the degree and number of points you specify. Deformable (degree 3) (left); Not deformable (degree 2) (right). Degree Specifies the degree of the arc. When drawing a high-degree arc, the output curve will not be the degree you request unless there is at least one more control point than the degree.
PointCount	Specifies the number of control points.
2Point	Draws the circle from the two ends of its diameter. 2Point steps Pick the start of the diameter. Pick the end of the diameter.
3Point	Draws a circle through three points on the circumference. 3Point steps Pick three points that define the circumference. Radius Specifies the radius and orientation for the circle after two points have been picked. Radius steps Pick a location or type a radius value. Pick a direction to orient the circle.
AroundCurve	Draws a circle perpendicular to a curve. AroundCurve steps Select a curve and pick the center of the circle on the curve and a radius or diameter.
FitPoints	Draws a circle by fitting to selected point objects, curve and surface control points, and mesh vertices. FitPoint steps Select point objects or control points. A minimum of three points or control points is required.
Tangent	Draws a circle tangent to curves. Tangent steps Pick the first tangent location on the first curve. Pick the second tangent curve, or type a radius. Pick the third tangent curve, or press Enter to draw the circle from the first and second tangent locations. FromFirstPoint Forces the circle or arc to go through the first picked point on the curve instead of allowing the point to slide along the curve. Point Allows a point that does not have to be a tangent point on a curve. Radius The circle is restricted to the specified radius. If a tangent point exists on the second curve that meets the radius requirement, the tangent constraint will appear at that point as you drag the circle. Vertical Draws a circle perpendicular to the construction plane. Vertical steps Pick the center and a radius or diameter. Radius/Diameter Toggles between accepting a radius value and a diameter value. To switch between radius and diameter Pick a location or type a value.
Orientation	Specifies an orientation not on the construction plane. To specify orientation Pick a direction that will be perpendicular to the circle plane. Perpendicular direction (1); Circle plane (2).
Circumference	Specifies the circle's circumference. To specify circumference Type the circumference value at the command line or pick a location to show the circumference length.
Area	Specifies the circle's area. To specify the area Type the area value at the command line or pick a location to show the area value.

Command-line options

Deformable

Draws a NURBS approximation of the curve will be created with the degree and number of points you specify.

Deformable (degree 3) (left); Not deformable (degree 2) (right).

Degree

Specifies the degree of the arc.

When drawing a high-degree arc, the output curve will not be the degree you request unless there is at least one more control point than the degree.

PointCount

Specifies the number of control points.

2Point

Draws the circle from the two ends of its diameter.

2Point steps

Pick the start of the diameter.
Pick the end of the diameter.

3Point

Draws a circle through three points on the circumference.

3Point steps

Pick three points that define the circumference.

Radius

Specifies the radius and orientation for the circle after two points have been picked.

Radius steps

Pick a location or type a radius value.
Pick a direction to orient the circle.

AroundCurve

Draws a circle perpendicular to a curve.

AroundCurve steps

Select a curve and pick the center of the circle on the curve and a radius or diameter.

FitPoints

Draws a circle by fitting to selected point objects, curve and surface control points, and mesh vertices.

FitPoint steps

Select point objects or control points.
A minimum of three points or control points is required.

Tangent

Draws a circle tangent to curves.

Tangent steps

Pick the first tangent location on the first curve.
Pick the second tangent curve, or type a radius.
Pick the third tangent curve, or press Enter to draw the circle from the first and second tangent locations.

FromFirstPoint

Forces the circle or arc to go through the first picked point on the curve instead of allowing the point to slide along the curve.

Point

Allows a point that does not have to be a tangent point on a curve.

Radius

The circle is restricted to the specified radius. If a tangent point exists on the second curve that meets the radius requirement, the tangent constraint will appear at that point as you drag the circle.

Vertical

Draws a circle perpendicular to the construction plane.

Vertical steps

Pick the center and a radius or diameter.

Radius/Diameter

Toggles between accepting a radius value and a diameter value.

To switch between radius and diameter

Pick a location or type a value.

Orientation

Specifies an orientation not on the construction plane.

To specify orientation

Pick a direction that will be perpendicular to the circle plane.

Perpendicular direction (1); Circle plane (2).

Circumference

Specifies the circle's circumference.

To specify circumference

Type the circumference value at the command line or pick a location to show the circumference length.

Area

Specifies the circle's area.

To specify the area

Type the area value at the command line or pick a location to show the area value.
