Beginners guide to 3D modeling

3D modeling necessitates a unique blend of technical and creative abilities. It’s a career-oriented field with a lot of promise, but it also makes a terrific pastime. 3D modeling offers a variety of applications that may be useful in everyday life, and it’s a talent worth learning.

While it’s a frequent notion that the admission barrier is relatively high, this is not the case. Even if you don’t want to invest any money, it’s not difficult to get started with 3D modeling these days. You’re OK to go as long as you have a computer with a respectable processor and some form of the graphics card.

When dealing with 3D, you usually start with a basic geometric form (such as a cube, sphere, or cylinder) and alter it using various modifiers until it matches what you’re attempting to achieve. Of course, that’s an oversimplified form; in fact, most complicated models are made up of a number of smaller shapes that are each adjusted separately.

Free vs Paid Tools

Free 3D modeling was often a discipline that required expensive commercial software to enter. 3ds Max, Maya, Cinema 4D, Houdini, and other prominent software packages are still in use today. Blender, which is essentially the only viable free 3d modeling software, existed back then, but it was not the Blender that many of us are familiar with now.

In terms of functionality, UI/UX, simplicity of use, and community support, Blender can easily compete with the main competitors on the market today.

With that in mind, Blender is the way to go if you don’t want to spend a lot of money on a commercial programme. It can take you as far as other popular options on the market.

One of the most common criticisms of 3D modelling is that it needs powerful gear to get started. That is no longer the case.

When dealing with sophisticated modifiers or when your scene becomes extremely huge, editing may take a while, but you won’t be doing any of that when you first start.

A faster computer immediately corresponds to quicker rendering speeds when it comes to rendering. This implies that if you have the patience to wait for your renderings to finish, you can get away with a low-powered machine.

Establish your Goals of 3D Modeling

If you’ve decided to pursue 3D modeling for financial benefit rather than just as a creative pastime, you’ll want to concentrate on a few key areas. Selling static models is a fantastic place to start however it’s a busy business.

You might also consider selling your renderings in other formats, such as conventional art (prints or t-shirts). 3D modelers are also in high demand in the game development industry.

In any event, you should research the market you’re going to join and identify the essential abilities you’ll need to succeed. In this sense, each area of 3D modeling is distinct, and you’ll have to spend some time experimenting until you’ve found what works best for you.

Components of a 3D Model

You’ll need to understand the fundamentals of 3D modelling on a basic level. The most significant terms are as follows:

  • The smallest component of a 3D drawing is the vertex, which is a single point.
  • A straight line connecting two vertices is called an edge. Edges aid in the definition of a 3D model’s form.
  • Any shape made up of connected straight lines is called a polygon. The number of sides and the extent of the angles determine the kind of polygon (equilateral, equiangular, regular, irregular, cyclic, convex, concave).
  • Face: The most fundamental component of a polygon mesh. It contributes to the filling of the area between the edges. A face is formed when flat areas of a model are “covered.”
  • Mesh: A collection of polygons with faces, edges, and vertices that are linked. One or more 3D meshes make up a 3D object.

Low-Poly Models

Low-poly models are another important idea in 3D modeling. This is a type of polygonal mesh with a tiny number of polygons. (The image above is a nice illustration.) Subdivision modeling, animation, and rigging are all examples of low-poly modeling.

If you’re creating a model for use in a real-time engine like Unity, low-poly models are ideal. Their key advantages are the ease with which they may be loaded, viewed, and edited. There won’t be much detail in a basic model, but you’ll be able to work on it fast.


This 3D modelling approach, unsurprisingly, is used to create solid objects. Its goal is to ensure that all 3D drawings are accurate geometrically. Solid modeling is more difficult than the other two types since it needs recreating the model’s outside and inside.

The use of solid modeling in the production, animation, design, and visualization of functional models is beneficial. The designer can see how the design appears and functions from the beginning.


A mathematical approach for visualising or presenting solid 3D things is surface modelling. It focuses on a 3D model’s exterior aspect, allowing you to examine it from various perspectives on solid surfaces.

Surface modelling is less difficult to deal with than solid modelling, but it is more difficult than wireframe modelling. It’s mostly employed in architectural drawings and video game animations.

Here are a Few Tips for You

Now that we’ve covered some of the issues and remedies that modeling rookies may face, let’s go over some additional tips.

  • Select the best 3D modeling software: Start using beginner-friendly 3D modeling software.
  • First, learn the fundamentals: Begin by altering basic forms such as cubes or triangles. Get a grip on the many aspects and approaches that go into bringing your ideas to life.
  • Pay close attention to the environment: It will appear more realistic if the background is appropriate for your project.
  • Define and imagine the model’s appearance, as well as how you’ll begin modeling and how the finished model should seem.

It’s always possible to recycle: To save time, reuse meshes.
