CAD for Engineering Solved Exam Questions
Course Introduction
CAD for Engineering introduces students to the fundamentals of computer-aided design (CAD) as used in modern engineering practice. The course covers essential CAD software tools and techniques for creating precise 2D drawings and 3D models, enabling the design and visualization of engineering components and systems. Students will develop skills in drafting, dimensioning, assembly modeling, and file management while understanding the role of CAD in the design, analysis, and manufacturing processes. Practical exercises and design projects provide hands-on experience, preparing students to effectively communicate engineering ideas and work collaboratively in design teams.

Answer: For most measurements, you hold the micrometer with the work held in the hand, while the spindle is turned down on the feature with the thumb and index finger of the other hand. Do not remove the micrometer from the object before taking the reading. If the reading cannot be seen because of the position of the micrometer, set the lock nut before sliding the micrometer off the object.
Q3) Give another name for the micrometer caliper.
Answer: A micrometer caliper is commonly called a micrometer.
