GLOSSARY

 Axis: An axis is an imaginary reference line that serves to define a symmetry

Base Plane: A base plane is a spatial field defined simply by a horizontal plane or figure placed on a contrasting background. Perceptible colour contrast, texture or tonal change between a surrounding area and a surface can define this spatial field

Circle: A flat geometric surface contained within a circle with defined area. It is the portion of the plane limited by a circumference. In other words, it is the bounded region of the plane

Colonnade: Colonnade, row of columns generally supporting an entablature (row of horizontal moldings), used either as an independent feature (e.g., a covered walkway) or as part of a building (e.g., a porch or portico). ... Ruins of the colonnade of the forum at the ancient city of Gerasa, modern Jarash, Jordan

Columns: It is an elongated vertical support that allows the weight of a structure to be supported. As an element of the architecture, the columns are classified differently according to the link they maintain with the rest of the components of the structure

Cubes: A regular polyhedron that is bounded by six equal squares, whose adjacent sides form right angles and whose three dimensions are also equal. It is a solid box-shaped object that has six identical square faces

Curve: It is the line formed by an infinite succession of points that change direction in a constant and smooth way. They are the lines that are constituted in a curved way; but in turn their points go in different directions.

Cylinder: A cylinder is a geometric body that can be generated by rotating a line around an axis, and around a flat curved surface at the base. A right cylinder can be defined as a figure generated from a rectangle that rotates around an axis that is one of its sides

Cylindrical Surface: The cylindrical surface is made up of parallel lines, called generatrices, which contain the points of a plane curve, called the cylinder directrix.

Depth:is the distance of an element from a horizontal reference plane when said element is below the reference.

Dimensions: the term perspective is used in graphic arts to designate a representation, generally on a flat surface (such as paper or canvas), of a motif as perceived by the eye, so that its three-dimensional configuration can be intuited.

Edges: Edge is understood as the limit that an object or figure can have and that marks the end of its surface in relation to that of the external environment. The edge is usually represented by a line

Geometry: Geometric is that linked to geometry, which is the specialty of mathematics oriented to the analysis of the magnitudes and properties of figures in space or on a plane. A geometric drawing, therefore, is one that is made following the rules of this discipline.

Ground: Surface of a room on which one walks or is; also called floor. Horizontal plane of projection on which the object rests or on which the observer is; also called geometral plane, horizontal plane of projection.

Horizontal: Line or figure in which all points are at the same height. That goes from side to side, like the horizon. In descriptive geometry, it refers to the condition of a line or plane

Hyperbola: Hyperbola is a conical, open, flat and two-branch curve defined as the locus of points in the plane whose difference in distances to two other fixed ones, called foci, is constant and equal to the magnitude of the major axis.

Line: The line in the technical drawing is a fundamental entity or perhaps the most important of this. It is used to help illustrate and describe the shape of objects. ... Hidden line: used to show surfaces, edges or corners of objects that are hidden from view, and are usually represented by segmented lines

Mass: Mass drawing refers to representing the solidity of the subject by masses of tone or color, without emphasizing lines or edges. Also called weight and modeled drawings, they are one of the basic exercises in figure drawing along with contour drawing and gesture drawing. Shape and mass.

Parabola:  The parabola is the locus of the points in the plane that are equidistant from a fixed point called the focus and a line called the directrix

Plane: A plane is a graphic representation made with technical means of a surface without making a projection. ... In Geometry, a plane is an ideal object that only has two dimensions, and contains infinite points and lines; are fundamental concepts of geometry together with the point and the line

Pyramids:  It is a polyhedron bounded by a base, which is a polygon with one face; and by faces, which are coincident triangles at a point called the apex. The apex or cusp is also called the vertex of the pyramid, although a pyramid has more vertices, as many as the number of polygons that limit it.

Segment: the segment is a fragment of the line that is between two points, called extreme or end points

Shape: is the appearance of everything we see (drawings, sculptures, objects, people, animals, etc ...). The forms arise as a consequence of the interpretation of the images. We identify all the objects and beings that surround us through their form.

Solids: A Solid or Geometric Body is a geometric figure of three dimensions (length, width and height), which occupies a place in space and consequently has a volume.

Sphere: (spherical surface) is the set of points in three-dimensional space that have the same distance from a fixed point called the center; both the segment that joins a point with the center, as well as the length of the segment, is called the radius.

Surface:  We understand as surface the infinite points of contact that a body or volume has with space.

Surface rotation:  Twist, geometric rotation of a figure or a physical body. ... Geometric transformation equivalent to a rotation, determined by a center, an angle and a direction. Geometric rotation of a figure or a physical body..

Texture: Element of Visual Language. It is called this way not only to the external appearance of the structure of the materials, but to the treatment that can be given to a surface through the materials

Translational surface: It is a rectilinear movement according to an established direction by which each point of a figure moves the same distance

Triangle: Flat surface limited by three lines that are cut two by two. They are convex polygons with their diagonals coinciding with the sides

Vertex: From the perspective of geometry, the vertex is the name given to the point that marks the union between the segments that originate an angle or where a minimum of three planes merge. The cusp of a cone or pyramid is also known as a vertex, as is the maximum or minimum point of a curved line.

Vertical: Perpendicular to the horizon plane. It is applied to the line or plane that is perpendicular to the horizon or to a horizontal plane. In descriptive geometry, it refers to the condition of a line or plane, to be perpendicular to the horizontal or geometrical projection plane.

Volume: The line in the technical drawing is a fundamental entity or perhaps the most important of this. It is used to help illustrate and describe the shape of objects. ... Hidden line: used to show surfaces, edges or corners of objects that are hidden from view, and are usually represented by segmented lines

Width: It is called the smallest dimension of the plane figures; the corresponding largest dimension is the length
