In Discover you researched possible reasons for the creation of three-dimensional models. For example, you may have found out that landscape architects, developers, and city planners use software to model projects. People in these professions often create physical models to show clients and the public what the end product will look like.

 

You have likely seen models of buildings, bridges, rail lines, ships, aircraft, machine parts, and vehicles of all types. In Section 2 you will use digital media to practise building 3-D models from 2-D orthographic views.

With a partner, or with a group of people, review what you did in Try This 2 by discussing the following questions:

  • How might a top view not show all the details required to build a 3-D model?

  • How could you add blocks to a 3-D object without changing one of the views? Explain.
