ITPEC IP October 2019 Question 88
Which of the following is an appropriate case example of improvement in business operations using CAD?
Explanation
Converting design information to a database to share and reuse design drawings — CAD (computer-aided design) is the use of computers in design work.
With CAD, drawings and 3D models are created and stored as data rather than on paper. Kept in a database, existing designs can be searched, shared among designers and reused for new products with small changes, which shortens design time and keeps drawings consistent.
Answer (c)
Why not others:
- •(a) — IC tags on products for inventory control and shipment monitoring are an RFID application in logistics, not design
- •(b) — sensors that monitor and keep the temperature on production lines are process control in factory automation
- •(d) — robots running an unmanned production line are factory automation (FA) and CAM, which use computers in manufacturing, not in design
Key rule: CAD supports designing, CAM supports manufacturing; ask whether the improvement is in making drawings or in making products.
