Computer-Aided Design


                  Whether it is designing a sewer system or a skyscraper, the work of any civil
                  engineer will, at some point, require  computer-aided design (CAD). CAD
                  is computer software that civil engineers use to create precise, detailed
                  drawings or technical illustrations. Engineers can create  two- dimensional
                  or three-dimensional ( 3-D) models using CAD. These programs are part
                  of a civil engineer’s training and everyday work. A version of CAD, called
                  AutoCAD, is a standard tool used by most civil engineers around the world.
                  In addition to being able to design buildings and other projects on the
                  computer, CAD helps engineers solve geometry and physics equations
                  associated with their designs. Files can be easily saved and sorted. Build-
                  ings, water lines, roads, and other parts of a project can be placed in a va-
                  riety of positions within a job site on the computer. CAD also has a feature
                  that allows an engineer to send a CAD image to a 3-D printer that creates
                  a model of the design. High school students can start learning CAD at
                  school, at home, or at a technical school in their community. Experience
                  with CAD can be a valuable asset when starting an engineering education.

               the Deepwater Horizon cleanup turned out to be harmful to the
               ecosystem of the gulf. Solving these kinds of problems effectively
               but safely are among the many important challenges facing envi-
               ronmental engineers.

               Materials Engineers

               Materials engineers, who are also civil engineers, help develop
               new materials for use on projects ranging from submarines to
               spacecraft and from highways to computer chips. They are ex-
               perts in the properties of metals, ceramics, concrete, wood, fab-
               rics, and other materials used to build things. They must know
               how various materials will stand up to extreme temperatures, how
               they will conduct electricity, and whether they will corrode or lose
               their strength over time.
