Design Computing is when computers are used to help in the process of designing things like cars, buildings, art, and other kinds of products. By using computers, designers can make things faster and more accurate than they could by hand. For example, a car designer can use a computer program to help them create a 3D model of their car and experiment with different looks and features to make it look better or make it perform better. Computers can also do a lot of calculations and simulations to help designers understand how their designs will work, both on paper and in real life.
