| A.In the past, technical drawings for industry and architecture were drawn by hand, i.e. people worked at drawing boards with drawing equipment. These hand-drawn diagrams provided clear technical information but were slow and expensive to make. Nowadays, working drawings are done on computers, which is much quicker. B. Computers can also: 1. save, change, and recycle the drawings; 2. make 3D images; 3. make drawings bigger or smaller; 4. keep an electronic library of standard parts; 5. Make symmetrical images of components; 6. make accurate and consistent drawings. C. A good way to explain the advantages is to think about architectural drawing. Features such as windows and doors can be moved until the architect likes the building. Images of the rooms are created in 3D so the viewer can “walk” through the rooms. Designers can also experiment with different arrangements of furniture and colours. * (the text is from: “Engineering” Workshop by Lindsey White, OUP; Unit 7, pg.8, ex.4) |
