5 Best Free 3D Modeling Software

May 23, 2019

Although there are ready-made free 3D models on the Internet, for many people, what attracts them most is that they can design and create their own models. The problem is that modern professional-grade CAD software is mostly expensive, and programs like Solidworks or Zbrush cost at least $1,000, and most regular users are not willing to pay for it. Fortunately, there are a lot of free CAD software in the industry, and can provide professional-level design capabilities. 

This article introduces the best 5 free online CAD software tools.

Blende is a comprehensive 3D modeling suite that offers a wide range of professional-grade features and modules and is now synonymous with free 3D software. Blender is often referred to as TheBlenderProject because it is more than just a piece of software, it's a complete community dedicated to creating the most complete 3D modeling and animation development solution. And this software is open source, every day developers provide new modules and plug-ins, and the software is constantly updated.

The user evaluation of this software is relatively high, and the occasional complaint is that its interface is a bit poor. However, this is because the community is too large and needs to provide too many tutorials online, sometimes it will make some users confused. In addition, Blender is more than just a 3D design, it allows users to research and even create their own animations, and some of the animations created with Blender will even make Pixar's top designers blush. Overall, the Blender community is very powerful and impressive.

Target users: People who need advanced 3D modeling capabilities, a variety of gorgeous effects


Wrench designed in TinkerCAD

TinkerCAD is produced by the industry standard software company AutoDesk and is a friendly primary 

3D CAD software. Although he is not the most powerful software on this list, TinkerCAD offers many 

amazing features, and it is especially suitable for first-time users, but it is also suitable for the most experienced CAD users. This software provides a quick and easy way to model. For example, if you want to make a cube, you can drag and drop the cube, enter your measurement data, and then it's done.

TinkerCAD is a "what you see is what you get" tool, he has a lot of pre-design available, users can modify it according to their needs. Although it is weak in terms of artistic modeling, it can be used in a quasi-system 3D design in a very simple and friendly way. In addition, TinkerCAD has a very professional online community that allows users to see the potential of this basic, fully cloud-based 3D CAD software.

Target users: junior CAD designers and people who want to create basic 3D models


Fusion360 offers a lot of tutorials to make great models

AutoDesk also offers Fusion360, a student-oriented product that is free for educators and academic 

institutions. Fusion360 is much more powerful than TinkerCAD, but it's not necessarily a product that beginners can use directly, so AutoDesk provides a complete tutorial package for those who want to research and learn.

Much like TinkerCAD, all the files provided by Fusion360 are completely cloud-based. It allows users to save various models in the project and test them to see the pressure they will be exposed to when interacting with each other. Although there are no large suites available in the way of character modeling, there are some small features that allow users to use grid creation and fine styling.

In addition, the software has a large number of 3D printer integrations that can be used with slicing software to further simplify your workflow.

Fusion360 is an advanced version of TinkerCAD. This software is very suitable for those who have mastered the basics and operations of TinkerCAD.

Difficulty: 3/5

Feature set: 4/5

Target users: Requires a higher level of customized users than TinkerCAD with many engineering features.


OnShape offers multi-part assembly and mechanical test integration

In terms of functionality, OnShape is arguably the most impressive software in this article. It was created by two former Solidworks CEOs, JonHirschtick and John McEleney, completely free and completely cloud-based.

OnShape is undoubtedly the most versatile and lightweight of the free online CAD software options, and the only app with Android and iOS apps that allows you to view and modify designs from your tablet or smartphone. OnShape provides many of the similar features previously mentioned in Fusion360, such as the ability to simulate multi-part components.

And in terms of engineering integration, OnShape is not inferior, it perfectly simplifies the entire engineering workflow from start to finish to a completely cloud-based model. In addition, there are a large number of custom features that will appeal to many CAD users who are familiar with other programs such as AutoCAD or Solidworks. In 2016, Onshape added a feature called 

FeatureScript, a new open source programming language for creating and customizing CAD functions. 

There is no doubt that OnShape is currently the most powerful free CAD software on the planet.

Simulating and drawing dinosaurs in Sculptris

Sculptris can transfer engineering components to modeling software from ZBrush authors, which can be modeled using virtual clay balls, which allow push, pull, pinch, etc. to create a coherent grid and instantly 3D print. Sculptris has some minor drawbacks, because sometimes you need to fix a model like MakePrintable, but Sculptris's extremely user-friendly design and intuitive interface far exceeds its shortcomings, and there are few 3D animal modeling experiences in the small ones. 

Make a pig model with very small instructions in a short period of time.

If you already have ZBrush, Sculptris can be integrated with the software via the GoZ button, allowing you to further model your project in the ZBrush interface. As far as creating static 3D models, the possibilities of Sculptris are almost endless, and there are plenty of works of art and tutorials to choose from. Sculptris is ideal for beginners in 3D modeling and is ideal for 3D printing.
