Explain the importance of sketching in the design process.
Sketching helps in brainstorming, problem-solving, and refining design solutions before committing to detailed work.
Sketching is a waste of time and resources in the design process.
Sketching is only necessary for finalizing designs, not for initial ideation.
Sketching limits creativity and innovation in design.
What are the key steps involved in the engineering design process?

Detailed design, prototyping, problem identification
Research, brainstorming, evaluation
Problem solving, testing, final implementation
How can CAD software be beneficial in the design and analysis of products?
CAD software benefits product design by enabling physical prototyping
CAD software benefits product design and analysis by enabling precise design creation, virtual testing, and cost-effective analysis before physical prototyping.
CAD software increases the cost of product analysis
CAD software is not useful for virtual testing
