X → Circle Conversions

This topic provides a reference table for all automatic type conversions to circle, sorted by merit.

Fair Conversions

This section lists all fair conversions to the circle type. A 'Fair' conversion indicates the types involved are closesly related in a data layout sense, though not necessarily in a conceptual sense. For example booleans and integers, or points and vectors. Although these conversions may fail or narrow, it is nevertheless considered decent practice to rely upon them in algorithms.

From	Explanation
sphere	Extracts the equator of the sphere.

Plausible Conversions

This section lists all plausible conversions to the circle type. A 'Plausible' conversion indicates a non-straightforward, but a still reasonable conversion between two types that share a salient quality, or where one is an obvious sub-type of the other. For example curves and intervals, or points and planes. Any plausible conversion can also be achieved through the explicit use of standard components.

From	Explanation
arc	Completes the arc into a full circle.
curve	Creates the spanning circle containing the curve.
identifier	Extracts the circle of the referenced Rhino curve object.
plane	Creates a unit circle oriented on the plane.
point2	Creates a unit circle centered on the 2D point.
point3	Creates a unit circle centered on the point.
polyline	Creates the spanning circle containing the polyline.
rectangle	Creates the spanning circle containing the rectangle.
triangle	Creates the spanning circle containing the triangle.
tube	Extracts the circular cross-section from the tube base.
vector	Creates a circle at the origin normal to the vector direction.

Strange Conversions

This section lists all strange conversions to the circle type. A 'Strange' conversion indicates a peculiar, but occasionally sensible, translation between types. However, it is equally likely that the conversion was not intended and thus represents a mistake in the algorithm design, which is why this conversion level is the default for showing conversion warnings in the Grasshopper interface. Examples in this category include the conversion between colours and booleans, or between circles and triangles. Any strange conversion can also be achieved through the explicit use of standard components.

From	Explanation
box	Creates the spanning circle containing the box base.
complex number	Creates a circle at the origin intersecting the complex number coordinate.
integer	Creates a circle at the origin with the specified radius.
number	Creates a circle at the origin with the specified radius.
