3D CAD Models used in the Design Process

Do you know what helps engineers to conceptualize their ideas and bring them to life? 3D CAD modeling is an obvious answer to engineers’ needs. No doubt engineers have an irrepressible creative streak.

Still, they need an outlet, preferably a comprehensive outlet that helps them explore the various concepts and develop them in a form that the audience can easily perceive. Thanks to CAD models that allow professionals to make more accurate representations and modify them as and when required to improve the quality of designs.

What is 3D CAD modeling?

CAD is an acronym for Computer-Aided Design Technology. This class of software is a combination of tool and visualization palettes for designers, architects, and engineers.

Whether it is product designing, tool designing, engineering drawing, or anything related to the design and manufacturing world, 3D CAD models are the starting point for every project.

They are a mathematical representation of the three-dimensional surfaces of an object via specialized software.

These models can be developed manually as well as automatically. But since they are software-made, there is the least chance of fault, or even if it occurs, it can be easily identified and resolved during the initial stages.

What are the types of 3D CAD models used in the design process?

With the advancements in technology, several techniques have been evolved so far for creating 3D models. This article will walk you through the three major types of 3D modeling- solid, wireframe, and surface. Continue reading!

Solid modeling

Solid modeling includes working with three-dimensional shapes. The shapes may vary between spheres, cubes, n-sided prisms, but they act like building blocks when placed together.

Some engineers even utilize two-dimensional portrayal sketches that are then modified and optimized accordingly to deliver three-dimensional models. While others add solid over solid and develop more intricate designs, the final solid models are the same.

This type of software modeling is beneficial only when the flat surfaces or basic bend of consistent radii are included. Moreover, it is relatively straightforward for users as well as in terms of computer power.

Wireframe modeling

Wireframe modeling is used in design processes where the surface is complex and curved. When designing, you find that the basic building blocks that worked for solid modeling are too obtuse for some applications.

Therefore, wireframe models are used to provide the finesses for such complex forms. In this type of modeling, shapes are represented as a network of vertices, and each geometric face comprises a minimum of three vertices.

Surface modeling

Surface modeling is another type of 3D CAD modeling that takes the next step up to represent complexities. There are top-notch professional applications that demand smooth surfaces and seamless integrations.

For all such applications, surface modeling is the most efficient solution. Moreover, it can produce even those visual representations that are next to impossible in the real world. It is the most upgraded type of modeling that represents the shape and curvature of the objects by depending upon the guiding lines.

3D CAD technology is used in various industries from architecture, engineering, medical to gaming, etc. It promises to reduce the time and effort, increase the efficiency of the professionals and reduce capital investment.

Moreover, it also provides significantly better results as it allows all designs to be vetted out during the designing stage, which would otherwise be done only during the manufacturing stage. Hence, it would not be wrong to say that this design technology has made work simple and life simpler for designers and engineers across the globe.
