Most modern professional CAD software is expensive. Programs such as Solidworks or Zbrush cost at least $ 1,000, and most ordinary users are not willing to pay for it. Fortunately, there are many free CAD softwares in the industry, and they can provide professional-level design capabilities.


NO.1 Blender

Blender is a comprehensive 3D modeling suite, which provides a large number of professional-level functions and modules, and has now become synonymous with free 3D software. Blender is often called TheBlenderProject because it is not just a software, but a complete community dedicated to creating the most complete 3D modeling and animation development solution. And this software is open source, developers provide new modules and plug-ins every day, and the software is constantly updated.


This software has high user ratings, and occasionally complains that its interface is a bit poor. However, this is due to the huge community and the need to provide too many tutorials online, which can sometimes confuse some users. In addition, Blender is more than just 3D design modeling. It allows users to research and even create their own animations. Some animations created using Blender can even make Pixar’s top designers blush. Overall, the Blender community is very strong and impressive.

The target users of wrenches designed in TinkerCAD: junior CAD designers and designers who want to create basic 3D models.


NO.2 TinkerCAD

Following is the wrench designed by TinkerCAD.

KerTinkerCAD is produced by 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 also provides a lot of amazing features. He is especially suitable for first-time users, but it is also suitable for the most experienced CAD users. This software provides a number of quick and easy modeling methods. For example, if you want to make a cube, you can drag and drop the cube, enter your measurement data, and you’re done.


KerTinkerCAD is a “what you see is what you get” tool. He has many pre-designed options to choose from, and users can modify it according to their needs. Although it is weak in artistic modeling, it can perform 3D design of quasi-system in a very simple and friendly way. In addition, TinkerCAD also has a very professional online community that allows users to see the potential of this basic, completely cloud-based 3D CAD software.

NO.3 Fusion360

Fusion360 provides a lot of tutorials to make great models


DeAutoDesk also offers Fusion360, a student-oriented product, which is free for educators and academic institutions. Fusion360 is much more powerful than TinkerCAD, but it is not necessarily a product that beginners can use directly, so AutoDesk provides a complete tutorial suite for those who want to specialize and learn.

Much like TinkerCAD, all files provided by Fusion360 are completely cloud-based. It allows users to save various models in a project and test them to see the stress they will experience 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 create and fine sculpt using meshes.

In addition, this software also has a large number of 3D printer integrations, which can be used with the slicing software to further simplify your workflow. Fusion360 is an advanced version of TinkerCAD. For those who have mastered the basic knowledge and operation of TinkerCAD, this software is very suitable.

Target users: Users who need a higher level of customization than TinkerCAD with many engineering functions.


NO.4 OnShape

OnShape provides multi-component assembly and mechanical test integration

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

OnShape is without a doubt the most versatile and lightweight of the free online CAD software options, and the only one with Android and iOS applications that allows you to view and modify designs from your tablet or smart phone. OnShape provides many similar features previously mentioned in Fusion360, such as the ability to simulate multi-component components.

In terms of engineering integration, OnShape is not inferior either, it perfectly simplifies the entire engineering work flow from beginning to end into a completely cloud-based model. In addition, there are plenty of customization features that will appeal to many CAD users 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 features. There is no doubt that OnShape is the most powerful free CAD software on the planet.

NO.5 Sculptris imitates and draws dinosaurs in Sculptris

Sculptris can transfer engineering parts to modeling software from the authors of ZBrush. This software can use virtual clay balls for modeling. It allows push, pull, pinch, etc. to create a coherent mesh, and it can be instantly 3D print. Sculptris has some slight disadvantages, because sometimes you need to repair models like MakePrintable, but Sculptris’ extreme user-friendly design and intuitive interface far exceed its disadvantages. The small articles have almost no 3D animal modeling experience and can Make a model of a pig in a short time with very small instructions.

If you already have ZBrush, Sculptris can integrate with the software via the GoZ button, which can 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 art works and tutorials to choose from online. Sculptris is great for beginners in 3D modeling, and it’s great for 3D printing.
