A convention is a set of agreed, stipulated, or generally accepted standards, norms, social norms, or criteria, often taking the form of a custom.
In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces.
Extrusion is a process used to create objects of a fixed cross-sectional profile.
Forging is a manufacturing process involving the shaping of metal using localized compressive forces.
The horizon or skyline is the apparent line that separates earth from sky, the line that divides all visible directions into two categories: those that intersect the Earth's surface, and those that do not.
Infinity (symbol) is a concept describing something without any bound or larger than any natural number.
Injection moulding (British English) or injection molding (American English) is a manufacturing process for producing parts by injecting molten material into a mould.

Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile.
Three-dimensional space (also: 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point).
