Activity 2.1 Isometric Sketching
Introduction
How do reading the face of a clock and sketching isometric pictorials relate to each other? Picture a cube in your mind. All of the surfaces of the cube form right angles with their adjacent faces. If you were to draw an isometric pictorial of the cube, you would see that the edges point toward 2 o’clock and 8 o’clock, 4 o’clock and 10 o’clock, and 6 o’clock and 12 o’clock. This idea helps when sketching isometric pictorials on writing surfaces that do not have isometric grids.
Isometrics are a common pictorial used both for concept sketches and to represent designs in technical drawings.

Procedure
In this activity, you will develop your isometric sketching skills by first drawing isometric views of objects that are already given in an isometric orientation. You will apply your sketching skills in later exercises to sketch orthographic views of objects that are not given in isometric orientation and to represent your ideas and designs.

Conclusion
1. What are the advantages and disadvantages to using an isometric pictorial compared to using an oblique pictorial in technical drawings?
2. What is the difference between a two-dimensional sketch and an isometric sketch?
3. Why do designers use tonal shading?
