One important element of a project notebook is sketches.
Drawing sketches for your designs allows you to depict complex
information. In particular, sketches are useful for portraying
three-dimensional objects. Since a sketch is an informal depiction
of a concept, it doesn't have to be very precise. Typically, sketches
show the basic form of a concept although they can also include
more detailed drawings. Sketches become more specific as a project
progresses. Many sketches can then be re-drawn for a final report.
