As we prepare students to be innovators in the world, they will need to know how to communicate design ideas effectively. Even in the age of digital design, 2D drawings are still useful in communicating design ideas and details. Knowing how to create a 3D object from a 2D drawing (3D visualization) is a critical skill. Most individuals recognize its usefulness when following illustrated assembly instructions for furniture and other structures. Engineers, architects, tradesmen, and others use 2D technical drawings to communicate how different parts of an object look and how they go together.  Doctors use flat x-ray images to determine the severity and direction of bone breaks. Clothing designers, landscapers, and even game developers use 2D drawings when communicating designs in their work environments.In this lesson, students will explore technical drawing terminology and build 3D structures by interpreting 2D diagrams.
