CAD Fundamentals
Pre-Test Questions
Course Introduction
CAD Fundamentals introduces students to the principles and applications of Computer-Aided Design (CAD) using industry-standard software tools. The course covers essential concepts such as 2D drafting, dimensioning, geometric construction, and basic 3D modeling. Students will learn how to interpret technical drawings, create accurate digital representations of mechanical components, and apply best practices for design documentation. Hands-on tutorials and practical assignments enable students to develop foundational skills necessary for advanced design work in engineering, architecture, and related fields.

Q1) When sketching, it is preferable to be able to move the paper around.
A)True
B)False
Answer: True
Q2) Keeping views aligned in a multiview sketch makes the sketching and understanding easier.
A)True
B)False
Answer: True
Q3) Describe the characteristics of a good pencil and leads to use for sketching. Answer: The pencil should have a soft lead. A common number 2 pencil works fine or an automatic 0.7- or 0.9-mm pencil with F or HB lead is also good. The pencil lead should not be sharp. A dull, slightly rounded pencil point is best.
Q4) Briefly describe how sketching is a form of communication.
Answer: Sketching is fast visual communication. The ability to make an accurate sketch quickly can often be an asset when communicating with people at work or at home. Especially when technical concepts are the topic of discussion, a sketch can be the best form of communication.
