How does CAD (Computer-Aided Design) benefit structural mechanics?

The benefit of CAD (Computer-Aided Design) in structural mechanics primarily stems from its capability to enhance accuracy and facilitate complex simulations. When engineers utilize CAD software, they can create detailed 3D models and designs that represent the structures with high precision. This accuracy is critical in aerospace applications, where even the smallest error can have significant consequences.

Moreover, CAD allows for the simulation of various loading conditions and material responses, enabling engineers to test the performance of their designs under real-world scenarios without the need for physical prototypes. This reduces the time and costs associated with the design process and leads to more effective and efficient engineering solutions. By providing tools for complex simulations, CAD helps to identify potential issues early in the design stage, ultimately improving the overall safety and reliability of the structures being designed.

In contrast, while options regarding increasing material costs, simplifying traditional sketching, and restricting design modifications do not align with the primary advantages offered by CAD, they reflect misconceptions about its functionalities and impacts on the structural design process.
