X → Brep Conversions

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

Direct Conversions

This section lists all direct conversions to the brep 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
box	Converts the box into a brep with six untrimmed faces.
region	Converts non-disjoint regions into breps.
sphere	Converts the sphere into a single face brep.
SubD	Converts subdivision surface of up to 10k faces into breps.
surface	Converts the surface into an untrimmed brep.
tube	Converts the tube into a brep.

Fair Conversions

This section lists all fair conversions to the brep 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
cage	Creates a brep from the cage volume boundary.

Plausible Conversions

This section lists all plausible conversions to the brep 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	Creates a brep from the arc interior.
circle	Creates a brep from the circle interior.
curve	Creates a brep from the curve interior.
identifier	Duplicates the referenced Rhino brep, surface, or extrusion object.
polyline	Creates a brep from the polyline interior.
rectangle	Creates a brep from the rectangle interior.
triangle	Creates a brep from the triangle interior.

Strange Conversions

This section lists all strange conversions to the brep 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
view	Create a brep representing the view frustum.
