X → Line Conversions

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

Direct Conversions

This section lists all direct conversions to the line type. A 'Direct' conversion indicates a relation between very related types, such as integers and numbers, or 2D and 3D points. Though note that even these conversions can fail due to out-of-bounds issues, or be narrowing due to reduction.

From	Explanation
polyline	Creates a linear approximation of the polyline's overall path.

Fair Conversions

This section lists all fair conversions to the line 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
arc	Creates a linear approximation of the arc.
circle	Creates a linear approximation of the circle.
curve	Creates a linear approximation of the curve.
point2	Creates a line from the origin to the point.
point3	Creates a line from the origin to the point.
rectangle	Creates a line along the longest rectangle axis.
vector	Creates a line from the origin along the vector direction.

Plausible Conversions

This section lists all plausible conversions to the line 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
box	Creates a line along the longest box axis.
identifier	Creates a line representation of the referenced Rhino curve object, if it is linear.
sphere	Extracts the axis line of the sphere.
