Have you ever wanted to create a 3D CAD model of something but didn’t know how? Well, you’re in luck! In this blog post, you will learn everything about 3D CAD modeling, how it works, the software commonly used in the process, 3D modeling techniques, and finally culminate by learning how 3D CAD modeling is used in real life to solve various problems and challenges. 

So whether you’re an experienced designer or just starting out, keep reading as we will teach you everything you need to know about CAD 3D modeling. We’ll discuss the basics of the process and show you how to create amazing 3D designs using CAD software. Let’s get started!

What is 3D CAD Modeling?

CAD modeling is a process of creating 3D models using Computer-Aided Design software. This software allows designers to create accurate and realistic models that can be used for various purposes, such as product development, architectural rendering, and engineering analysis. CAD modeling is essential for anyone who needs to create three-dimensional designs

You need to keep a few things in mind when CAD modeling. First, you need to make sure that you choose the appropriate 3D design software and have the latest version. Second, you need to create a detailed plan for your model. This plan should include all of your model’s dimensions and the colors and materials you will use. Third, you need to be patient when creating your model. The process can take some time, but it will be worth it in the end.

Now that you know the basics of CAD modeling, let’s take a look at how 3D modeling works. 

How Does 3D Modeling Work?

CAD software typically includes a library of standard shapes and objects that can be inserted into the software’s workspace. These shapes can be modified using a variety of tools, such as extrusion and rotation. More complex objects can be created by combining multiple basic shapes.

Once the model is complete, it can be exported to a file format that can be read by other CAD software or manufacturing equipment. This allows the object to be produced using rapid prototyping or other methods.

CAD modeling is a powerful tool that can create complex objects and shapes. With the help of CAD software, designers can quickly and easily develop models that can be exported for manufacturing or other purposes.

How are three-dimensional models created? This is a question that many people ask themselves, especially when they come across an attractive 3D model. The answer, however, is relatively simple. 3D models are created using 3D design software using various 3D modeling techniques. There is several 3D model maker software available that one can use for 3D CAD modeling. Still, we recommend using SelfCAD as it can perform the tasks that most industry-standard programs can do.

Having looked at how 3D modeling works and the best 3D design software, it’s essential now to look at the 3D modeling techniques for 3D CAD modeling. Different 3D CAD modeling techniques are available for creating 3D models, but the one you choose depends on the design you would like to develop and its purpose. Let’s have a look at the three main 3D modeling techniques used in creating designs.

3 Main 3D CAD Modeling Techniques

The three main 3D CAD Modeling techniques available include Polygonal modeling, Parametric Modeling, and Digital Sculpting.

Polygon Modeling

Polygon modeling is a 3D CAD technique that uses polygons as the basic building blocks. Polygons are typically triangles or quads but can also be other shapes. Polygon modeling is a very versatile technique that can be used for a wide variety of applications, from developing 3D models for computer games to creating detailed engineering drawings.

There are several benefits to using polygonal modeling for your subsequent 3D CAD modeling. First, it is relatively easy to create complex shapes with polygons. Second, polygons can be easily subdivided, which allows for a high degree of detail. Third, polygon models can be exported to various formats, and they can easily be modified, making them compatible with many different software packages. Finally, polygon models can be animated and rigged easily, making them suitable for use in character animation and special effects.

Creating organic shapes with polygons is also easier when compared to other methods, and it is also effortless to render.

Parametric Modeling

Parametric modeling is a type of polygon modeling where a set of parameters defines the shape of an object. These parameters can be changed to modify the object’s profile, making it a very versatile technique.

Parametric modeling is used in many different fields, such as engineering, architecture, and product design. This type of modeling allows for creating complex shapes and designs accurately and comprehensively.

This 3D CAD modeling technique has many advantages over other modeling techniques. Perhaps the most notable benefit is its ability to create highly detailed and accurate models. It is also used to develop parametrically adjustable models, which can be easily modified according to specific needs or requirements. Finally, parametric modeling can generate multiple versions or iterations of a design, which is often valuable for the development and prototyping stages of product design.

Many different 3D CAD modeling software applications offer parametric modeling capabilities. Some of the most popular include Solidworks, Autodesk Inventor, and PTC Creo.

Digital Sculpting

Digital sculpting is a 3D CAD modeling technique that allows for the creation of highly detailed models. It is often used for creating characters and creatures for video games, movies, and other digital media.

Digital sculpting involves using 3D sculpting brushes to create 3D models from scratch. These tools can produce various shapes and forms, making digital sculpting an interesting 3D CAD modeling technique.

Uses of 3D CAD Modeling

3D CAD modeling has become an essential tool in many industries today. The following are some of the key services of 3D CAD modeling. Here are just a few of the ways that 3D CAD modeling is being used today:

Product Design: Perhaps the most obvious use for 3D CAD modeling is in the product design process. With CAD, engineers and designers can create models of products that can be used to test for function, fit, and finish before any physical prototypes are ever created. This saves time and money and allows for much higher accuracy and precision in the final product.

-Reverse Engineering: In some cases, a product already exists, but no drawings or models are available. In these cases, 3D CAD modeling can be used to create a digital model of the existing product. This process, known as reverse engineering, can be used to create new products compatible with the existing ones or create a replacement part for an existing product.

-Prototyping: Creating physical prototypes of products is still an essential part of the design process, even with CAD. 3D printing technology has made it possible to quickly and easily create prototypes using CAD models. This allows designers and engineers to test the form, fit, and function before production.

-Visualization: One of the significant advantages of CAD models is that they can be used to create realistic renderings and animations of products. This is valuable for marketing purposes as it can give potential customers a realistic idea of what a product will look like and how it will work. It can also be used to create training materials for new employees.

-Manufacturing: In many cases, the CAD model of a product can be directly used for manufacturing purposes. This is especially true with CNC machining and 3D printing, where the CAD model can be used to generate the toolpaths necessary to create the final product.

Marketing: 3D CAD modeling is a powerful tool for marketing. Using 3D models to create images and videos of your products can give customers a better idea of what they’re buying and increase your chances of making a sale. If you haven’t tried using 3D CAD modeling for your marketing efforts yet, we suggest giving it a shot. You may be surprised at how effective this strategy can be. 


3D CAD modeling has revolutionized the way products are designed and manufactured. It allows engineers and designers to create a virtual product model that can be used for prototyping, testing, and even manufacturing. The benefits of using 3D CAD models are many, and businesses that don’t take advantage of this technology are at a serious disadvantage. If you want to stay competitive in today’s marketplace, you need to start using 3D CAD modeling to design your product.
