Go to: Related nodes. Attributes.

Compute a non rational circular arc (bspline form).
The degree of the created arc can be linear or cubic and is controlled using the attribute "degree". The number of spans of the curve can be controlled using the attribute "sections".
The computed arc's center, sweep angle and the normal of the plane containing the arc can be queried using the output attributes "center", "sweep" and "normal" respectively. The created arc is available at "outputCurve" and is non-rational.
