The illusion of three-dimensional form, space and distance can be conveyed in a contour drawing through the use of varied line-weight (darker lines in the foreground / paler lines in the distance) and perspective.

The angle that these techniques are applied may remain constant within a drawing, or it may change in response to the angle and direction of the forms. For example, cross-hatching may flow around the surface of an object in a similar direction as cross contour lines. These techniques are also a great way to create the illusion of texture (see our article about observational drawings).

Blind Contour Drawing : A blind contour drawing contains lines that are drawn without ever looking at the piece of paper. This forces you to study a scene closely, observing every shape and edge with your eyes, as your hand mimics these on paper. The aim is not to produce a realistic artwork, but rather to strengthen the connection between eyes, hand and brain: a reminder that, when drawing, you must first learn to see.

A cross contour drawing contains parallel lines that run across the surface of an object (or radiate from a central point), such as those that appear on a topographical map or a digital wireframe. The lines can run at any appropriate angle (sometimes at multiple angles) and may continue across objects and into the background. Cross contour drawings typically follow the rules of perspective, with lines drawn closer together in the distance and further apart in the foreground. In this type of drawing, the illusion of three-dimensional volume is created entirely with line.
