This wire drawing exercise ‘using line to create space’ is completed by students within a 3D Art class, working over photographic portraits. Having a base image to work from (this could also be an earlier observational drawing) makes the process of transferring from two-dimensional to three-dimensional much easier.
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.
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).
Continuous Line Drawing Exercises: This drawing method is great for sketchbooks and drawing from life. It can be an excellent starter activity, with drawings completed on large, inexpensive paper that can be scanned / edited / cropped and used in other ways within your projects.
