    • Answer: Based on my experience and skills, my salary expectations are in the range of $[Lower Bound] to $[Upper Bound]. However, I am open to discussing this further based on the specifics of the role and the company's compensation structure.

16. What are your preferred units of measurement in CAD?

    • Answer: I am comfortable working with both metric (mm) and imperial (inches) units and can easily switch between them based on project requirements.

17. Explain your understanding of orthographic projection.

    • Answer: Orthographic projection is a method of representing a three-dimensional object in two dimensions using multiple views (top, front, side) to show its shape and dimensions accurately.

18. What is the difference between a block and a symbol in CAD?

    • Answer: A block is a reusable group of objects that can be inserted multiple times into a drawing. A symbol typically represents a specific element (e.g., a door or window) and often includes attributes.

19. How do you create and manage layers in your CAD drawings?

    • Answer: I create layers with descriptive names related to the elements they contain (e.g., "Walls," "Doors," "Electrical"). I use layer properties to control visibility, color, and linetype to organize and clarify the drawing.

20. What is your experience with CAD standards and conventions?

    • Answer: I'm familiar with [mention specific standards, e.g., ANSI, ISO]. I understand the importance of consistency in line weights, text styles, and dimensioning to ensure drawings are clear, accurate, and easily understood by others.

21. How do you handle conflicting requirements or design changes during a project?

    • Answer: I communicate effectively with the design team, project manager, and client to resolve design conflicts. I carefully document all changes and revisions, ensuring everyone is informed and agrees on the final solution.

22. Explain your understanding of geometric constraints in CAD.

    • Answer: Geometric constraints are relationships defined between objects in a CAD model (e.g., parallel, perpendicular, concentric). They help ensure accuracy and prevent errors when modifying the design.
