WOODWORKING
Chapter 2PICTORIAL DRAWINGS
Introduction:
When preparing to construct a woodworking project, it is important to draw a pictorial - a two
dimensional drawing of a three dimensional image. Pictorial drawings not only provide you with a
realistic picture of what the final project will look like, but the process of drawing the pictorial will also
help you work through the construction process in your mind, discover problems in your design, and
promote artistic creativity to liven up your desired product. Simply put, a pictorial allows you and others
to imagine the possibilities.
There are two different types of pictorials: Parallel Projections and Perspective Projections.
Parallel Projections:
In a parallel projection, the lines of the drawing representing each side of the object are parallel to one
another, such as illustrated below. As you can see, there are different types of parallel projections
(oblique, diametric, isometric, and trimetric). The type chosen is determined by the purpose of the drawing
(manufacturing or marketing), and which projection will best communicate the needed information.
Parallel projections are often used in engineering and machine work.Perspective Drawing:
In a perspective drawing, the lines “fade
away” to a vanishing point and represent a
true-to-life image of the object.
Perspective drawings are often used for
artistic presentations, such as in
architecture, and are more conducive for
marketing or selling your product.Unit I: Project Preparation
