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.

A planar analysis drawing simplifies complex curved surfaces into flat planes, using straight lines. This process helps students to think about the underlying structure of objects and results in an analytical drawing, that is rather mechanical in appearance.

This article contains exercises for Art students who wish to produce contour line drawings, cross contour drawings, blind drawings and other types of line drawings. It is a teaching aid for high school Art students and includes classroom activities, a free downloadable PDF worksheet and inspirational artist drawings.

Here is a collection of line drawings from famous and less well known artists, to inspire high school Art students and teachers. This section is continually updated. Enjoy!
