Responsive computer-aided design

Responsive computer-aided design, also called CAD, is a way of using computers to help create and design things. It works by creating a digital 3D model or drawing and then changing it in response to what you do on the computer. For example, you can move the 3D model around with your mouse, change the color, size, shape, and other characteristics of the design, and even add objects to the design. Responsive CAD makes it easier to design and create things quickly, and with more accuracy than doing it by hand.
