How to Make 3D Models for Beginners

By Vaibhav Patel

In 3D computer graphics, 3D modeling (or three-dimensional modeling) is the process of developing a mathematical representation of any three-dimensional surface or object (either inanimate or living) using specialized software. The product is called a 3D model. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. The model can also be physically created with 3D printing devices. Models may be created automatically or manually. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts like sculpting.

3D Design Guide for Beginners

This 3D Design Guide will talk about the basics of modeling and the best software that can be used for it. It also recommends the best software for beginners to start with for modeling.


Let’s start this 3D design guide with Representation. Almost all 3D models can be divided into two categories:

    • Solid– These models define the volume of the object they represent (like a rock). These are more realistic, but more difficult to build. Solid models are mostly used for visual simulations like those in the medical and engineering fields. They’re also used for CAD and specialized visual applications like ray tracing and constructive solid geometry.

  • Shell/boundary– These models represent the surface, e.g. the boundary of the object, not its volume (like an infinitesimally thin eggshell). These are easier to work with than solid models. Almost all visual models used in movies and video games are shell models.                                                                                                                                         3d design guide


Next in our guide is the software that helps you design. 3D software enables engineers and architects to design, inspect, and manage engineering projects within an integrated graphical user interface (GUI) on a personal computer system. Most applications support solid modeling with boundary representation (B-Rep).

Best Software for Beginners

Google SketchUp is the best software for beginners to starting design. The tools are easy to understand and use. Check out these video tutorials to learn more about SketchUp.

    Blender is Free and while daunting at first, I find that when written by folks who are using it, the economy of action, is the goal and not ease for the beginner. The thing is, of course, nobody is a beginner forever and the joys of an economy of action are. I used Autocad for many years and used LISP to bring complex actions to fewest commands, but am still annoyed at having to hit so often.

    You can also mention a free software called nanoCAD. Here’s the link for the website:

    Woow thanks this is great…. I so interested in making stuff using 3D printer,i learnt how to use auto card a year ago but I could not continue bcs my laptop got bust and they were no resources in terms of what I can do with 3D drowning
