The Circle command draws a circle from a center location and a radius.
The Deformable option draws a NURBS approximation of the curve will be created with the degree and number of points you specify.
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.
Specifies the number of control points.
The 2Point option draws the circle from the two ends of its diameter.
The 3Point option draws a circle through three points on the circumference.
Pick three points that define the circumference.
Specifies the radius and orientation for the circle after two points have been picked.
|1.||Pick a location or type a radius value.|
|2.||Pick a direction to orient the circle.|
The AroundCurve option draws a circle perpendicular to a curve.
The FitPoints option draws a circle by fitting to selected point objects, curve and surface control points, and mesh vertices.
Select point objects or control points.
A minimum of three points or control points is required.
The Tangent option draws a circle tangent to curves.
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.
Allows a point that does not have to be a tangent point on a curve.
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.
The Vertical option draws a circle perpendicular to the construction plane.
Pick the center and a radius or diameter.
Toggles between accepting a radius value and a diameter value.
Pick a location or type a value.
Specifies an orientation not on the construction plane
Pick a direction that will be perpendicular to the circle plane.
Specifies the circle's circumference.
Type the circumference value at the command line or pick a location to show the circumference length.
Specifies the circle's area.
Type the area value at the command line or pick a location to show the area value
Draw lines and curves
