Leonardo da Vinci's Vitruvian Man (c. 1485) Accademia, Venice. Drawing is a visual art that uses an instrument to mark paper or another two-dimensional surface. The instruments used to make a drawing are pencils, crayons, pens with inks, brushes with paints, or combinations of these, and in more modern times, computer styluses with graphics tablets or gamepads in VR drawing software.
A line drawing is the most direct means of expression. This type of drawing without shading or lightness, is usually the first to be attempted by an artist.It may be somewhat limited in effect, yet it conveys dimension, movement, structure and mood; it can also suggest texture to some extent.

Two-dimensional or three-dimensional objects are often represented through shade (darkness) or hue . Line art can use lines of different colors, although line art is usually monochromatic.
When part definition is defined mathematically via a solid model, the assertion that one cannot interrogate the model—the direct analog of "scaling the drawing"—becomes ridiculous; because when part definition is defined this way, it is not possible for a drawing or model to be "not to scale". A 2D pencil drawing can be inaccurately ...
The definition of the term, and its "borders" with neighbouring terms such as folk art and outsider art, has been a matter of some controversy. Naïve art is a term usually used for the forms of fine art, such as paintings and sculptures, made by a self-taught artist, while objects with a practical use come under folk art.

[9] Folk art: Folk art originally suggested crafts and decorative skills associated with peasant communities in Europe – though presumably it could equally apply to any indigenous culture. It has broadened to ...
Definition of the part via a 3D CAD model rather than via a 2D engineering drawing. Drawings may be printed (plotted) from the model for reference use, but the model remains the governing legal instrument. MBP: measurement between pins: threads, splines, gears (internal, female) (synonymous with MBW) (see also MOP, MOW) MBW: measurement between ...
