What is meant by line drawing?

Answer 1

A red-line drawings is essentially an intermediate drawing that shows corrections or changes to a previous drawing. The term red line literally comes from the (typically) red pen used to amend the drawings by hand. These changes mark-ups show changes made to the drawing subject matter during the manufactuer or construction of the product.

For example, piping drawings were developed at the onset of a project to build a new school. During the course of construction for that school, the piping contractors changes several elements of the design (pipe size, routing, orientation etc). At the end of the project, the constructor would "red line" the drawings showing those changes.

Red-lines are used to then develop record drawings. Record drawings, also called "as-builts" accurately reflect what was constructed and are used for future work and/or reference.

Answer 2

Two basic categories of drawing could be classified as: line drawing and tone (tonal or tonalist) drawing.

Line drawings (see Charles Dana Gibson or Al Hirschfeld) use lines to describe the form and features. This gives the drawing a "cartoony" feeling, since when we look at a person in real life, we don't see a heavy black line along their jaw. Ink or a sharp pencil are often used in generating line drawings.

Tonal drawings are made usually using the side of the pencil rather than the point, making thick sweeps of gray, building the form with value. It conveys the form as light describes it. It more closely resembles a painting than a line drawing. Charcoal is and ideal medium for tonal drawings. (see the drawings/studies of John Singer Sargent)

Answer 3

Art or technique of producing images on a surface, usually paper, by means of marks in graphite, ink, chalk, charcoal, or crayon.

It is often a preliminary stage to work in other media. According to Giorgio Vasari, disegno (drawing and design) was the foundation of the three arts of painting, sculpture, and architecture. Beginning in the Italian Renaissance, debate arose regarding the role of drawing, as some saw it as an independent art form and others saw it as a preliminary stage in creating a painting or sculpture. By the 17th century, drawings had definite market value; connoisseurs specialized in collecting them, and forgers began to exploit the demand. In the 20th century, the drawing became fully autonomous as an art form, figuring significantly among the works of virtually every major artist, and the line itself was exploited both for its representational and its purely expressive qualities.

or drafting

In yarn manufacture, process of attenuating a loose assemblage of fibres.

These fibres, called sliver, pass through a series of rollers, which straighten the individual fibres and make them more parallel. Each pair of rollers spins faster than the previous one. Drawing reduces a soft mass of fibres to a firm uniform strand of usable size. For synthetic fibres, drawing is a stretching process applied to fibres in the plastic state, increasing orientation and reducing size. In metalworking, drawing refers to the process of shaping sheet metal into complex, three-dimensional forms with metal dies. See also carding, wire drawing.

Answer 4

It is when you draw a picture using just parallel lines without crossing them in anyway. It does not mean though that the drawing cant have darker or lighter parts. You can also use different colours and softness's of pencils, as far as it stays in a parallel line. A vital tool will be a ruler to ensure no variation of direction of the lines.

Answer 5

A red line drawing is a drawing that is made to illustrate changes in fabrication/construction that have been made and that are different to the original drawing.In other words a drawn record of an agreed change to a drawing.

Answer 6

A continuous line drawing is a technique wherein the artist looks only at the subject and draws without lifting the pencil from the paper, and also does not refer to the drawing.
