Best Free CAD Software for Windows

Computer-Aided Design (commonly abbreviated as CAD) has become an integral part of the process by which the world advances.

CAD enables you to design anything from small electronic components to large buildings, dams, and more.

Naturally, as the majority of professionals use CAD programs to design things, they have become expensive. And, if you’re a student or a freelancer, the prospect of purchasing expensive CAD software becomes a pipe dream.

However, there is no need to be concerned as we have compiled a list of the top ten free CAD software that is just as good as the paid versions. So without further ado, let’s take a look at the best free CAD software available in 2021.

Best Free CAD Software for Windows

We’ve compiled a list of the top ten free CAD software applications you can use in 2021.

Best Free CAD Software for Windows 1

The list includes both free and premium software and the Student’s edition of premium software. The latter is advantageous if your institution uses a particular tool, and you must know as well.

1. FreeCAD

As the name implies, FreeCAD is free and open-source CAD software popular with both beginners and professionals.

If you are familiar with the fundamentals of CAD modeling, this is the software for you.

Free CAD Software

Due to FreeCAD’s multipurpose behavior and intuitive interface, an educator or programmer can also make the most of it.

Despite being a free tool, FreeCAD’s user interface is nearly identical to professional CAD software. Additionally, it includes a slew of features.

The Parametric Model is arguably the most crucial feature of FreeCAD. It enables you to go back and edit previous actions to achieve the best results.

Additionally, the software features a modular architecture, enabling you to install plugins to add the features you require.

Additionally, from the perspective of an advanced user, its ability to be integrated into an app via Python modules makes it quite useful.

Additionally, FreeCAD includes the Robot Simulation module, which enables you to study robots’ movement, and a rendering module that allows you to export your project to external renderers.

To summarize, FreeCAD is an excellent choice if you’re looking for free CAD software for beginners. I’d argue that professionals can use it as well, given the tools and features included.

2. nanoCAD

While nanoCAD is not completely free, it is significantly less expensive than its competitors. And it is for this reason that I have included it on this list.

It is a low-cost CAD application that includes advanced tools for sketching and creating 2D and 3D designs.

Free CAD Software

Whichever industry you work in – architecture, manufacturing, or mechanical engineering – this tool provides all the necessary drafting and drawing extensions.

The most appealing feature of nanoCAD is its complete compatibility with the DWG file format.

Therefore, if you decide to relocate your project in the future, this feature will protect you.

Additionally, nanoCAD includes several end-user APIs for automating complex CAD designs. It can benefit businesses that create similar products regularly without having to go through the difficult drafting phase.

Additionally, nanoCAD is a standalone application. As a result, those who prefer to work with desktop programs will appreciate the program’s appearance and classic toolbar design.

To summarize, if you’re willing to pay a one-time fee of $180 rather than a monthly or annual subscription, nanoCAD is an excellent choice.

3. Tinkercad

Assume you’re at a friend’s house when you receive a call to design a simple 3D model. While your friend’s PC does not contain any CAD software, you have access to a fast internet connection.

In such cases, Tinkercad provides a solution. It is a web-based solution for creating 3D digital designs. The best part about Tinkercad is that it requires no prior experience and is completely free to use.

Free CAD Software

The program lacks some of the features found in other CAD software. However, if you’re looking for a simple platform for designing models, particularly for 3D printing, Tinkercard is the best option available.

Additionally, Tinkercard is a member of the Autodesk family, which supports various integrations and file formats.

What I love most about Tinkercad is how it entices children to learn CAD. While this may not seem like an enticing prospect for young audiences, the lectures are a lot of fun.

There is a great deal to learn here. You can learn about 3D design, electronics design, and programming blocks, among other things. Additionally, tutorials are demonstrating how to create Minecraft models.

There is a gallery where you can view and share the work of other users. Additionally, Tinkercad integrates with 3D printing services, supports HTML5, and includes a robust geometry library.

Tinkercad is an excellent online platform for learning about computer-aided design (CAD), and it is the ideal CAD software for 3D printing, even more so when the service is free.

4. Onshape

Onshape is a cutting-edge CAD application that is renowned for its outstanding design repository and assemblies.

Onshape is a cloud-based design platform, in contrast to other software programs: standalone, standalone desktop applications.

Free CAD Software

You can use a browser to produce interactive solid and surface models without fear of losing your design progress.

As Onshape is a browser-based platform, all of your actions are automatically saved to the cloud, protecting you from data loss.

Loss of design progress is a significant concern in computer-aided design systems as your project grows larger over time.

Apart from that, Onshape includes three primary design tools: components, assemblies, and drawings.

From its unique database of architecture designs, you can produce extremely structured and detailed assemblies.

Additionally, you can easily import DWG, DW, or DXF files for drawing purposes if you previously worked with Autodesk.

You’re probably thinking that, as Onshape is a premium, expensive piece of software, why are we recommending it?

The software is completely free for students, educators, and hobbyists.

Therefore, what else do you require? Capable cloud-based design software that includes all of the necessary modern tools. Onshape is, in some ways, one of the best free CAD software available right now.

6. AutoCAD

AutoCAD requires little introduction to 3D modeling, as it has been an international standard for many years. Although it is a premium program, you can obtain a one-year student license for free.

If you were unaware, AutoCAD is also part of the Autodesk family, and it is prohibitively expensive for students.

Best Free CAD Software for Windows 3

However, the company recognizes that if students cannot use AutoCAD, they will not learn it.

And this will have a negative effect on future sales as those students graduate and become professionals.

AutoCAD’s student edition includes all of the software’s features. When compared to AutoCAD’s $200-per-month subscription plan, this student version is truly exceptional.

You could even create complex assemblies and a variety of metal designs in the program and simulate them. AutoCAD boasts an incredible array of advanced tools and palettes.

Additionally, AutoCAD includes a sizable amount of documentation that can be used to familiarize yourself with the tool’s basic and advanced features.

Therefore, if you are a student, I strongly advise you to download AutoCAD, which is completely free and includes many features.
