A “hit-and-trial” engineering design template typically involves a more manual and iterative approach to engineering design. This process is often characterized by a trial-and-error approach, where multiple iterations may be required to achieve the desired outcome. It involves a hands-on, sometimes intuitive process where adjustments are made based on immediate results and observations.

In contrast, engineering software provides a more systematic and computerized approach to design. It often incorporates advanced algorithms, simulations, and modeling techniques. Engineering software allows for precise calculations, detailed analysis, and optimization based on mathematical models and simulations.
