Chapter 3 Communicating Design Ideas
69
Sketching
Communication is central to design and making products. Objects
and ideas are often represented using lines and shapes such as the ones
shown in Figure 3-6. These are known as line drawings. Designers,
drafters, technicians, engineers, and architects must be able to make such
line drawings. It would be impossible to explain the parts in Figure 3-7
without drawings.

Reducing Carbon Footprint through Communication
A carbon footprint is the amount of carbon dioxide and other greenhouse
gases a person or organization produces over a specific period of time.
Many companies are now using satellite and video communication systems
to hold business meetings across the country. This reduces their carbon
footprint by avoiding the fossil fuel emissions needed to travel across the
country—or across the world—by automobile, train, or airplane.
Think about your daily routines. Can you think of any way to use
communication to reduce your personal carbon footprint?
