Even in 2024, engineering without CAD design is possible, but it would likely be less common and more challenging due to the widespread adoption and benefits of CAD technology. However, in certain scenarios or industries where CAD might not be accessible or practical, traditional engineering methods could still be employed. Here’s how engineering might proceed without CAD design in 2024:

Manual Drafting and Sketching:

Engineers may resort to manual drafting and sketching using pen and paper or digital tablets. While less efficient than CAD, it allows for the creation of basic design concepts and layouts.

Prototyping with Rapid Prototyping Tools:

Rapid prototyping tools such as 3D printers, laser cutters, and CNC machines could be used to create physical prototypes based on hand-drawn sketches or conceptual designs.

Mathematical and Analytical Calculations:

Engineers would rely heavily on mathematical calculations, analytical methods, and theoretical principles to analyze and validate designs. Advanced computational tools and software packages could aid in complex calculations.

Traditional Manufacturing Techniques with Modern Tools:

Traditional manufacturing techniques like machining, casting, and molding may still be utilized, albeit with the assistance of modern tools and machinery for improved precision and efficiency.

Physical Testing augmented with Simulation Tools:

Physical testing of prototypes would still be essential for validation, but simulation tools and basic computational analysis could be used to supplement testing efforts, providing insights into design performance.

Collaborative Workflows and Documentation:

Collaboration among team members and stakeholders would rely on traditional communication methods such as meetings, drawings, and written documentation.

While engineering without CAD design in 2024 is conceivable, it’s important to acknowledge that CAD technology offers numerous advantages, including faster design iterations, better visualization, simulation capabilities, and collaborative workflows. Therefore, in most engineering practices, CAD remains an indispensable tool for efficiency and productivity.
