tackling viva questions We will explore common question categories illustrate effective answer strategies and highlight the practical applications of CAD skills in realworld scenarios I Common Categories of Viva Questions CAD lab viva questions generally fall into several overlapping categories A Fundamentals of CAD Software Question Type Explain the basic functionalities of specific CAD software eg AutoCAD SolidWorks Fusion 360 Describe the user interface command structure and key features Answer Strategy Structure your answer systematically Begin with an overview of the softwares purpose and applications Detail core functionalities like sketching 2D3D modeling constraints assemblies rendering and animation Illustrate your understanding with specific examples from your lab projects B Geometric Modeling Techniques Question Type Explain different geometric modeling techniques wireframe surface solid modeling Compare and contrast their advantages and disadvantages How did you use specific technique in your project Answer Strategy Clearly define each technique highlighting its underlying principles Use diagrams to illustrate the differences Discuss the suitability of each technique for different design tasks referring to specific examples from your projects For instance explain why you chose solid modeling over surface modeling for a particular component C Design Principles and Constraints Question Type Discuss the design constraints you faced in your project material properties manufacturing limitations cost etc How did you incorporate these constraints into your 2 CAD model Answer Strategy Demonstrate a thorough understanding of design principles like manufacturability ergonomics and aesthetics Explain how you considered and addressed various constraints during the design process Show awareness of realworld limitations and the tradeoffs involved in design decisions D Advanced CAD Features and Applications Question Type Explain the use of advanced features like parametric modeling FEA integration or CAM functionalities within your chosen CAD software Answer Strategy Clearly explain the benefits and applications of these features Provide concrete examples from your projects where you utilized these capabilities Discuss how these features enhanced the design process improved the quality of the final product or reduced design time II
