2. Perspective drawing technique was invented during the Renaissance period (1300-1500) Engineering Graphics

3. Parallel projection technique was invented during the Industrial Revolution period (1750-1850) Engineering Graphics

4. 2-D CAD systems were developed in the 1980s Engineering Graphics

5. 3-D CAD systems were developed in the 1990s Engineering Graphics The Boeing 777 is the first jetliner to be 100 percent digitally designed using three-dimensional computer graphics. Throughout the design process, the airplane was "pre-assembled" on the computer, eliminating the need for a costly, full-scale mock-up. Dodge Neon was designed using 3-D CAD system CATIA
