Final answer:
Computer-aided design (CAD) software is a soft technology that can be used in smartphones to design and create digital models. It allows engineers to easily make changes to the design and simulate how the parts will fit together.
Step-by-step explanation:
Computer-aided design (CAD) software is an example of a soft technology that can be used in smartphones. CAD enables engineers to design and create digital models of objects, including smartphone components. It allows engineers to easily make changes to the design and simulate how the parts will fit together.
For example, in the design of the Boeing 777 aircraft, a sophisticated CAD system called CATIA was used to design every part of the aircraft and ensure that they fit properly with all the other parts. This CAD system allowed engineers to communicate their designs with each other and collaborate on the project.
Overall, CAD software is a powerful tool that enables engineers to efficiently design and improve complex components, including those used in smartphones.
