ITPEC FE Morning October 2019 — Question 72 of 80
CAD (Computer-Aided Design) — creating product design drawings using a computer.
CAD stands for Computer-Aided Design. It refers to using a computer to create product design drawings from attribute data about the product's shape, composition, and other characteristics. CAD systems help engineers and designers visualize and model products digitally before physical production.
Why not others:
- (a) This describes CAE (Computer-Aided Engineering) — virtual testing and simulation without a physical prototype
- (b) This describes CAM (Computer-Aided Manufacturing) — converting design drawings into machine processing instructions
- (d) This describes MRP (Material Requirements Planning) — calculating required material volumes and timing from production schedules and BOMs
Key rule: CAD = Design/Draw, CAM = Manufacturing, CAE = Engineering simulation.
