What Is 3D Modeling Used For?

Three-dimensional (3D) modeling has revolutionized the way we design and market products. This technology has improved ideation and design in every single industry, from luxury cars to office chairs.

In this post, we’ll dive into the concept of 3D modeling and how it’s useful. We’ll also share why you should hire a 3D modeler for your business. Let’s start with what a 3D modeler is and what it’s capable of.

What Is 3D Modeling Used For?

3D modeling is used to create a three-dimensional design of a product or character. The idea is first drafted in its two-dimensional (2D) form on paper or computer software.

Then, an artist or 3D modeler uses dedicated software and polygonal modeling to convert this 2D idea into a 3D model. They break the 2D design into the smallest possible polygons and then reconstruct the shape in a virtual space.

The 3D model sits atop a base mesh and comprises vertices, lines, and edges. After constructing its frame, details are added using lighting software and other tools. The goal is to make the 3D model appear as real as possible. Because of its versatility, 3D modeling has exploded in several trades.

These three major industries use 3D modeling for breaking new grounds:


Architects have benefitted the most from 3D modeling. It has shortened the design process and created architectural models in a much more resource-efficient way.

Previously, architects designed miniature physical models of the entire building to visualize and weigh its practicality. In case there’s a change in plans, they had to redo the entire model from scratch.With 3D modeling, they can edit and improve the structure within the 3D modeling software. 

3D modeling can help you control architectural machinery. For example, you can link GPS systems to excavators and bulldozers, and then connect it all to the 3D modeling equipment. The 3D model of the worksite then determines the surface elevation at different points and the type of equipment required for it.


Another industry that has immensely benefited from 3D modeling is animation. Originally, animators had to draw each character frame by frame. This was expensive and time-consuming. With 3D modeling, they can use software to craft a 3D character whose animations can be controlled via the animation program.

Animators can easily modify every aspect of the character in the virtual space. It’s easier than ever to establish the texture, movements, and facial expressions of characters. This software can also establish scenery and environments.

Game Development

Perhaps the most stunning use of 3D modeling in game development is the introduction of immersive 3D games. Game developers have created entire worlds where gamers can virtually integrate into the fabricated world. They can create customized playable characters, explore, and engage with other players and non-playable characters. Red Dead Redemption and Monster Hunter World are two examples of these games.

Note that this is not the same as virtual reality. Although 3D modeling has helped improve VR worlds, 3D games are a different story. You can download these games on any device and do not need a VR headset to play them. Roblox and Minecraft are two popular examples of such games.

How to Start With 3D Modeling

How can you integrate 3D modeling into your organization or business? Below, we’ll walk you through the steps to get you started.

Learn the Art Yourself

The first and obvious approach is to learn how to do it on your own. There are several educational resources available online that can help you learn 3D modeling. 

However, note that it takes a minimum of four months to learn the basics. It might even take six to twelve months if you’re a slow learner or not very tech-savvy. Despite this time investment, there’s no guarantee that you’ll be able to produce the error-free model of your dreams. 3D modeling software is expensive on its own before you factor in the labor hours or time spent learning it.

Hire an Expert Freelancer

You can hire a professional 3D modeler. Keep in mind that because 3D models may require editing, you need to settle the terms for editing beforehand. Let the artist know if you’ll ask for revisions and if so, how many. We recommend offering an additional fee for revisions.

The risk of hiring a freelancer for 3D modeling is that you might become a victim of fraud. To avoid this, use a safe and reliable platform. Platforms like Escrow ensure that the payments are released only after you’ve received your end product.

Our Recommendation

We recommend first-time users hire a 3D modeler. When working with freelancers from Guru, you get an accurate picture of how much a 3D character model costs, personalized work, and professional results.
