3D objects created by CAD programs

How can transformations help you after geometry class? Geometry is the study of shapes and objects in the physical world. By manipulating objects, we learn about their properties and how they can be used to create more complex structures. Consider the field of Computer-Aided Design, or CAD.

CAD is an exciting field that uses computers to assist in making blueprints and three-dimensional designs. Engineers use CAD software applications to design residential and commercial buildings. Movie animators use CAD software to design and manipulate movie sets before they are built. Using CAD programs, a figure can be rotated, moved and reflected easily to achieve the visual effect that the designer wants.

In this lesson, you will construct your own transformations using accessible tools like graphing paper, transparencies, and interactive software.
