definition of planes

When we speak of a plane, we are referring to the geometric surface that does not have volume (that is, it is only two-dimensional) and that has an infinite number of lines and points that cross it from one side to the other.

However, when the term is used in the plural, it is talking about that material that is elaborated as a graphic representation of surfaces of different types. The plans are especially used in engineering, architecture and design since they serve to diagram on a flat surface other surfaces that are regularly three-dimensional.

When we speak of planes in the plural sense, we refer to those forms of diagramming on a two-dimensional surface (usually paper, although it is also done on computer media) different types of three-dimensional structures. In this sense, the architectural or engineering plans become a kind of cartography that aims to graphically put the organization and arrangement of the elements that make up the structure to facilitate their understanding.

Unlike what happens with map cartography, the engineering, design or architecture plan does not require a superior projective system as it does with maps, since these are usually made on relatively small or delimited spaces. At the same time, it does not always need to be an exact representation of what is observed, but rather a diagram of its most important elements, their location and the connections that may exist between them. In many cases, the design plans may be the artist's personal creations and not based on the recreation of an existing space.

The plans as a graphic representation can also be urban plans, seeking in this case to diagram the different spaces of a city or town. This is especially used for tourism, as well as for urban planning and the implementation of public works.

Other uses of the term

Although the ones set out above lines are the most widespread uses of the term, or they are the ones that we first think about when this term arises, there are also other recurring uses of it in the language, such is the case of the one who refers to what plane is what is It is characterized by being smooth and flat, that is, it does not present a fold or relief on its surface, but rather it turns out to be very even.

On the other hand, the concept is widely used in colloquial language as a synonym for point of view, that is, the point of view from which an event or a question is analyzed. From the plane in which you analyze the question of unemployment, I do not agree at all.

In anatomy, we also find a reference for this word, because the anatomical plane implies the various parts into which the human body is divided and that allow its more detailed analysis and the easier identification of the structures that compose it, either externally and internally. By dividing the body into different planes, it is easier to know each part. These include: the sagittal plane, frontal plane, horizontal plane, and transverse plane.

And in the cinema and on TV, the use of the word shot has become the order of the day since it is linked to the shot with which a camera captures a person or a situation that is presented on stage. Even the subject of the shot tends to arouse controversies between artists and camera directors as a consequence that the former often consider that certain shots do not favor them and then argue about it with the director, who is in charge of marking the shots.
