Today, many architects, engineers, and designers use computer-aided design (CAD) as the main tool for creating designs, unlike in the past where the main design tool was the drafting table. For many years, computer-aided design was two-dimensional. Today, 3D CAD has become a popular architectural design option. Businesses benefit in many ways from both 2D and 3D CAD modeling.
1. Software Flexibility
CAD allows architects and designers to make design changes rapidly. Before CAD, architects had to redraw their designs altogether when making design changes. Today, architects can modify their designs and make changes on the fly. CAD also enables designers to simulate the behavior of their designs on the software. For example, engineers can use CAD to simulate airflow around engines. This means that CAD offers greater flexibility in design processes.
2. Design Flexibility
CAD facilitates rapid prototyping, which refers to the construction of physical prototypes during the design process. Rapid prototyping allows designers to test various aspects of their physical prototypes. For example, if the goal is to construct a steel structure, then the engineers and designers can create a prototype made out of acrylic. This will allow the engineers and designers to observe various aspects of the acrylic prototype such as stress with the structure. CAD provides engineers, architects, and designers with greater flexibility in the design and prototyping process.
3. Automatic Specification Checking
CAD allows designers and architects to check if their designs meet required specifications. In addition, it enables designers to observe designs during the early stages of the design process to ensure all design specifications have been met. In addition, clients can use CAD to check the progress of functional and semi-functional prototypes during the early design stages, which is not possible with the traditional design process.
Some CAD applications allow designers to check their product’s size in relation to other known products. This allows designers to compare their products against different objects to determine if the product meets the required measurement specifications.
4. 360-Degree Views
Many CAD applications can create 360-degree models of products with the aim of showing them off from all angles and better prepare the products for production and packaging. 3D CAD applications provide 360-degree views of products, which are necessary for most aspects of production and marketing. CAD applications save designers hours of sketching time.
CAD applications can be used to create realistic 3D models that can be used with video-editing software. Companies can use the models in their marketing campaign by incorporating them directly into their commercials.
CAD is a general term used to describe various technologies such as rapid prototyping, computer numerical control, component modeling, and design applications. CAD technologies were developed in the ‘80s and are now commonly used in various design and academia fields.
