Elevation (Technical Drawing)
Introduction
The technical drawing is a system of graphic representation of various types of objects, with the purpose of providing sufficient information to facilitate their analysis, help develop their design and enable their future construction and maintenance. It is usually done with the help of computerized media or directly on paper or other flat supports.
Graphic representation is based on descriptive geometry and uses orthogonal projections to draw different views of an object.
The objects, parts, machines, buildings, urban plans, among others, are usually represented in plan "Plan (architecture)") (top view, roof view, floor plan, roof, among others), elevation (front or previous view) and side (dimensions); A minimum of two projections (views of the object) are necessary to provide useful information about the object, depending on its complexity.
The views mentioned according to the orthogonal system are called fundamental because they belong to the fundamental trihedron, this trihedron is made up of the anterior, superior and lateral plane.
With the aim of unifying the language of technical drawing, internationally approved regulations were established, but each country has its national standardization body for the study and approval of the different Standards (in Argentina IRAM is the only organization that carries out this task). By applying these regulations, any plan can be interpreted by any professional in the corresponding area.[1][2].
Characteristics
Forms of expression
Technical drawing encompasses works such as sketches and/or sketches, schemes, diagrams, electrical and electronic plans, representations of all types of mechanical elements, "Plant (architecture)" plans of architecture, urban planning, etc., resolved through the help of geometric concepts, where mathematics, Euclidean geometry, various types of perspectives, scales "Scale (cartography)"), among others, are applied.
Media and supports
The drawing can be captured on a wide variety of materials, such as various types of paper, canvas or acetate (); It can also be projected on a screen, displayed on a monitor.
