CAD modeling is the use of computers to create detailed models of objects before they are physically produced. It is used by engineers, architects, and artists in various industries. CAD models can be simple or elaborate, and even animated. It is an essential skill for most engineers and has replaced pen and paper artists. While CAD software can be expensive, it greatly increases the speed and efficiency of the design process.
CAD modeling is used by many designers to create elaborate computer models of objects before they are physically produced. CAD stands for computer aided design. Engineers, architects and even artists use computers to assist in their design projects. Computers allow them to visualize their designs and tackle problems before they’ve expended the necessary resources to put them into physical form.
CAD modeling takes many different forms depending on the type of project. Some models are simple two-dimensional representations of various views of an object. Others are elaborate three-dimensional cross-sections showing every detail in great depth. Some CAD models are even animated, showing how all the components of the model work together to complete its function.
Many different professions make use of computer aided design. It is an important industrial art involved in automotive, aerospace, prosthetics, and fine art designs. The use of CAD modeling is widespread; anything from chairs to rockets can be designed with the help of computer programs. Among other titles, CAD modelers are referred to as CAD monkeys, designers and digital information engineers.
CAD began as an elite, knowledge-intensive design style accessible only to those with money and big engineering and computer skills. Over the course of its life, it has worked its way up to the personal computer. Almost anyone with access to a personal computer can acquire the software and skills needed to make simple CAD models.
Undergraduate engineering courses place a lot of emphasis on teaching CAD modeling. It’s an essential skill for most engineers, and mechanical engineers find it particularly useful. In the beginning, students learn the basics of the CAD program interface and how to apply their knowledge to specific projects. In more advanced classes, they learn the intricacies of 3D modeling and animation.
One CAD modeler can easily replace several pen and paper artists. This type of modeling greatly increases the speed and efficiency of the design work. CAD software, however, can be very expensive. Training for CAD designers can also be expensive. Therefore, vendors of CAD modeling technology are constantly working towards cheaper and more accessible software.
The design process is long and complex, and CAD modeling has had a profound effect on the development process. First, you need to create a general idea to solve a specific problem. Subsequently, this type of modeling is used to work out the specifics of the model design. At one time, this step would have involved several draftsmen making dozens of sketches and diagrams until a perfect model could be devised. Now you can continuously create, edit and refine a single CAD file until the object is ready for production.
