Cross Contour Drawing Exercises: This is an excellent way to gain familiarity with the volumes and three-dimensional forms in your project, producing analytical cross contour drawings that are suitable for sketchbooks or early preparatory sheets.
When we first picked up a pen or pencil and started making marks on paper, we began with line. Whether self-taught, through trial and error, or guided by others, we learned how line defines form, creates structure, divides a frame, traces contour, creates tonal variation (cross-hatching, for example) and leads the eye from one part of a work to another. Initially a mechanism for getting outlines onto paper – identifying edges – we begin to applaud lines for their own merit: celebrate their presence…whether a quiet flick of charcoal on paper or a streak of graphite.
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.
Wire Sculpture Line Drawing Exercise: This is an excellent activity for middle school students and for high school students, if it relates specifically to your project (and does not interfere with postage requirements, for those who need to post work away for assessment). Small wire experiments, using light-weight wire, can also be mounted to sketchbook pages.
