Drafting (also known as Technical Drawing)
Is the academic discipline of creating standardized technical drawings by architects, interior designers, drafters, design engineers, and related professionals. Standards and conventions for layout, line thickness, text size, symbols, view projections, descriptive geometry, dimensioning, and notation are used to create drawings that are ideally interpreted in only one way.
A person who does drafting is known as a drafter. In some areas this person may be referred to as a drafting technician, draftsperson, or draughtsman. This person creates technical drawings which are a form of specialized graphic communication. A technical drawing differs from a common drawing by how it is interpreted. A common drawing can hold many purposes and meanings, while a technical drawing is intended to concisely and clearly communicate all needed specifications to transform an idea into physical form.

Types of Drawing (Drafting)
Line DrawingLine art is any image that consists of distinct straight and curved lines placed against a (usually plain) background, without gradations in shade (darkness) or hue (color) to represent two-dimensional or three-dimensional objects. Line art can use lines of different colors, although line art is usually monochromatic.
Free Hand DrawingA freehand drawing is simply a drawing done by hand without the use of tools or aids such as templates, stencils, tracing, etc.
Perspective Drawing
In the graphic arts, such as drawing, is an approximate representation, on a flat surface (such as paper), of an image as it is seen by the eye. The two most characteristic features of perspective are that objects are drawn:
- Smaller as their distance from the observer increases.
- the size of an object's dimensions along the line of sight are relatively shorter than dimensions across the line of sight.
Isometric DrawingA pictorial representation of an object in which all threedimensions are drawn at full scale rather than foreshortening them to the true projection. An isometric drawing looks like an isometric projection but its all linesparallel to the three major axes are measurable.
Orthographic Drawing
Is a means of representing a three-dimensionalobject in two dimensions. It is a form of parallel projection, where all the projection lines are orthogonalto the projection plane,[1] resulting in every plane of the scene appearing in affine transformation on the viewing surface. It is further divided into multiview orthographic projections and axonometric projections. A lens providing an orthographic projection is known as an (object-space) telecentric lens.
Oblique DrawingAre designed to show a three dimensional view of an object. It is a kind of a drawing that shows one face of the object in true shape, but the other faces on a distorted angle. Oblique is not really a '3D' system but a 2 dimensional view of an object with 'forced depth'.
