What advantage does CAD provide over traditional design methods?

The option that states CAD allows for complex simulations and quick modifications accurately highlights a significant advantage of using Computer-Aided Design (CAD) over traditional design methods. CAD software enables designers and engineers to create detailed 3D models that can be easily manipulated and modified, which is particularly beneficial in the iterative design process. This capability allows for rapid prototyping and testing of different design scenarios without the need for physical models, saving both time and resources.

Additionally, CAD tools often include simulation features that can analyze how a design will perform under various conditions, providing valuable insights that help in refining designs before any physical production takes place. This ability to promptly make changes and simulate outcomes leads to more efficient workflows and can enhance the overall design quality, offering a stark contrast to traditional methods that rely heavily on manual adjustments and time-intensive prototyping.
