Command-line options

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

  • PointCount: Specifies the number of control points.

Vertical
Draws a circle perpendicular to the construction plane.

2Points (or Diameter)
Draws the circle from the two ends of its diameter.

Steps:

  1. Pick the start of the diameter.
  2. Pick the end of the diameter.

3Points
Draws a circle through three points on the circumference.

Steps:

  1. Pick three points that define the circumference.

Tangent
Draws a circle tangent to curves.

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

AroundCurve
Draws a circle perpendicular to a curve.

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

Orientation
Specifies an orientation not on the construction plane.

Radius/Diameter
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.

Orientation
Specifies an orientation not on the construction plane.

Circumference
Specifies the circle's circumference.

Area
Specifies the circle's area.
