It’s hard to overestimate the role CAD software plays in modeling. It is widely used by professionals in engineering, architecture, graphic design, film and video game development. On top of that, since advanced technology is becoming more and more accessible for everyday users, many enthusiasts enjoy CAD modeling as a hobby.
Each year, new and more advanced CAD software, both commercial and free, appears on the market. In many cases, free programs are just as good - and sometimes even better - as expensive professional applications. That’s why it can be quite challenging not to get overwhelmed by options and pick the one that ticks all the boxes. We’ve put together this extensive list of free CAD programs to help you make the right choice.
The apps are divided into three sectors, each covering programs best suited for different levels of CAD proficiency: beginners, intermediate users and professional-level users. To avoid confusion it is important to mention that some of the programs are freemium, while others can be free only for select groups, such as students and teachers.
If you’re new to the world of CAD and 3D modeling software, and shaky on some of the basic terms, you should take a look at our mini-dictionary of CAD-related terms.
At first, CAD programs were developed only to work with 2D. It was possible to work only with top, front and side views of the model, just as you would if you designed without digital aid. Some CAD programs still offer only 2D features. More than that, many designers even prefer 2D modeling for some purposes. Unfortunately, it is very difficult to work on complex projects in 2D, that’s why most 2D CAD programs are aimed at working with simple technical geometry.
3D modeling, on the contrary, gives an opportunity to design complex profound models. 3D modeling technologies offers a mathematical representation of any surface of the objects in three dimensions, which cannot be implemented without technical software. 3D modeling makes it possible to create true-to-life designs, which can be then tested via physical simulations, animated or manufactured.
Surface modeling is a mathematical method typically used in CAD software. A surface 3D model is composed of a wireframe, which is amplified by descriptive surface data. Free-form surfaces, such as Bezier curves and NURBS, and some other types of surfaces are most common. Still, surface models don’t contain any information about the content of the model, which makes surface modeling less appropriate for 3D printing. Nonetheless, this type of modeling is widely used in 3D animation, graphic design and architecture.
Solid models on the other hand supply more data. They provide information on such physical properties, as volume, mass and the center of gravity of the model. This data makes it possible to physically manufacture an object from ground zero. This makes solid modeling a superior method of CAD, compared to surface one.
In this section, we’ll tell you about software most suitable for those taking their first steps on this exciting 3D modeling journey. Such software is quite user-friendly, and it will allow inexperienced owners learn from their mistakes and quickly adapt while learning more about the operating process.
3D Builder is a free CAD application, which allows to view, edit and print 3D designs from your home desktop. It was designed specifically for Microsoft and all of its platforms - Windows PC, Windows Mobile, Xbox and Windows HoloLens. You can download models created by other 3D Builder users in the app’s free library, modify them as you please and then 3D print them.
The 3D Builder app for Windows phone has one distinctive feature that is worth mentioning - you can scan objects in real life and turn them into 3D models using the phone‘s camera. To make that possible, you just have to take a series of photos of an object from several angles, so the app can use these pictures to make a 3D recreation of an object.
3DCrafter is a multi-functional CAD software application, designed for Windows OS by Amabilis Software. The app is developed for 3D design and animation.
One of the most prominent features of the program is its drag-and-drop control. This approach simplifies 3D modeling a great deal and allows even novice users to create the most complex and intricate 3D designs without effort. There is a number of starting basic shapes: cube, cylinder, sphere, torus, and cone. These shapes can be dragged and dropped into your workspace, where you then build, mold and paint your final design.
The free version of the app already has a very extensive building and editing tool set. Needless to say, 3DCrafter Plus and 3DCrafter Pro can offer even more helpful features, such as Create-a-Face, Duplicate, Auto Mirror, Clone, Split Faces, etc.
You can also create high-quality animations using this software simply by positioning your 3D objects in its right place frame by frame. Finished animations run smoothly and seamlessly, and can be easily shared in the form of AVI files.
Because there are so many functions in 3DCrafter, the interface of the app requires some getting used to. For those experiencing some troubles getting a hold of the program, Amabilis Software offers numerous tutorials free of charge.
3D Slash is a unique CAD software with a very intuitive approach to 3D modeling. Every 3D design created in 3D Slash starts from a cuboid shape. These cuboids of different sizes then can be modified into a desired object using the program’s set of tools, just like a statue being sculpted from a block of stone. The inspiration for this concept came from Minecraft, where you also can build the world by adding and breaking cubical shapes.
3D Slash’s building instruments literally make up a tool box. You can create your 3D objects using the hammer to remove a cuboid, the trowel to add one and the chisel to remove parts of the cubes. It is also possible to color the blocks with a brush and make other adjustments using such tools as the milling machine and the wood filler.
You can also project pictures onto your objects to guide your work or make an engraving. 3D Slash provides an opportunity to use a number of more familiar functions, such as copy, paste and rotate. It is possible to import readymade 3D objects in the app to modify or integrate them in your own designs. Finished 3D Designs can be saved in a variety of file formats, shared via links and printed true to scale.
3D modelling in this app is like playing a fun game, which makes it a great program for beginners. 3D Slash is available for Windows, Mac OS, Linux.
Today we are used to CAD software applications with interactive GUI interface and a standard set of tools. So it seems quite strange when people choose to write 3D objects as code instead of using apps that predict your every move. At the same time, using scripts for 3D modeling has its own advantages: you can easily change parameters of the model, fix your mistakes, or reuse pieces of code for other projects. Needless to say, learning such programs as OpenSCAD can be rather intimidating and time-consuming, that’s why apps like BlocksCAD exist.
BlocksCAD is a free cloud-based 3D modeling application that was developed as an introduction to OpenSCAD and other similar CAD programs. This software encourages children to pursue their love of science and learn math, logical thinking and coding concepts in a visual way. Objects, shapes and transformations are represented by colorful blocks that can be stacked together just like LEGO bricks. Finished models then can be exported in OpenSCAD or STL file formats for further 3D printing.
Though the program looks like a fun game, it is still possible to create a decent OpenSCAD script using the software. Once you master BlocksCAD, it should be fairly easy to switch to OpenSCAD, since you get a grip of how the changes in each individual block affect the code and the whole 3D design.
Leopoly was created with interests of those who only start to dabble in 3D modeling. This is a free browser-based software, created by ZSpace for educational purposes. Leopoly makes first attempts to build 3D objects easy and fun. It is important to understand that Leopoly is not a full-on CAD software, rather just a 3D sculpting app with CAD elements. Nonetheless, this is a perfect program to get entry level users interested and excited about 3D modeling.
In Leopoly, it is possible to browse the library of already existing models which then can be molded and shaped into new designs. Users can also upload their own STL and OBJ files into Leopoly for further tweaking and editing. If you are feeling creative, you can begin building your models from scratch. Digital sculpting allows you to sculpt 3D objects, and transform them by painting, engraving and embossing. Meanwhile, formshifting mode makes it possible to select a basic shape and start modeling from there. Finished designs then can be directly sent to the 3D printer.
LibreCAD is a free open source CAD app. In the program it is possible to import already existing designs for editing, or to create your own models from square one. Because of its famous user friendly intuitive interface, LibreCAD often serves as the very first app for those who only begin their CAD journey. Though LibreCAD can display isometric views, it still remains a strictly 2D designing app with very restricted maximum file size of 30 MB.
The core LibreCAD software can be extended by numerous add-ons and plugins, which add various features and enable import and export of different formats in the program.
Inspired by video games such as Minecraft and Monument Valley, MagicaVoxel is a free CAD software where you can modify cubical blocks into intricate 3D designs. The smallest constructional units in the program are voxels, which can be grouped and manipulated in many different ways.
In MagicaVoxel you can use drag-and-drop style tools, line tool for one. With this tool you can extract a line of blocks with a couple clicks of the mouse. Other tools allow to select, move, delete or change size of the groups of blocks. To streamline the modeling process, MagicaVoxel offers a number of predefined brushes and voxel patterns, which can be used to create more complex models, but it is possible to freehand simpler designs as well.
The app’s interface is uncluttered and neatly arranged, with rows of color palettes which can be used to paint voxels, and a range of render settings next to them. Color palettes can be customised or pre-downloaded into the program.
Still, working with the program’s tool-set can be a bit confusing at first. Some modes affect only the surface of the mesh, while others allow to select layers or work inside the volume of a mesh. On top of that, MagicaVoxel gives an opportunity to create simple 3D animations by duplicating and slightly modifying shapes.
Often it can be quite intimidating to get into 3D modeling, especially if you are interested in the artistic side of things more than in the technical one. In this case, 3D sculpting can become a gateway hobby which has a perspective to develop into professional career in 3D modeling. One of the most simple 3D sculpting apps is SculptGL. SculptGL is a completely free open-source app, which works in your browser and doesn’t require you to download any software to your desktop.
The concept of the app is very simple, building 3D objects using SculptGL is like working with clay. For this reason, even the most novice of users can create their designs right away with almost no previous learning.
The design starts with a ball of clay, which can be molded and modified by adding or removing layers of material in very wide brush strokes. Then, when the silhouette of the object is defined, you can switch to finer tools to work on smaller details. Unfortunately, since the app is free, some important functions are missing. For one, you cannot make holes or hollow out your designs, which can be a big problem in the printing process. That’s why you may need to use some other CAD software to make your designs printable. It is possible, as you can import and export the finished objects in OBJ, STL, and PLY file formats.
TinkerCAD is Autodesk’s free, browser-based 3D modeling program, which is famous for its intuitive interface and user-friendliness. Developed in 2010, TinkerCAD was designed to make 3D object creation accessible to the general public.
The application is based on a simplified CSG method and offers the users some primitive shapes that are either “solid” or “hole” to start their design. 3D objects are created by combining solids and holes together. These object then in turn can be assigned the property of solid or hole and used to create more complex designs.
Finished designs can be then published and shared in TinkerCAD’s gallery, as well as exported in STL, OBJ or SVG file formats, which can be then used for 3D printing or laser cutting.
Wings 3D is a free and open-source subdivision modeler, originally inspired by Nendo and Mirai from Izware. Its user-friendly icon-oriented interface needs little to no getting used to, which makes it a great app for beginners. Despite its simplicity, the app still packs a punch. Apart from the standard CAD tools, such as scale, move and extrude, the software offers a wide range of more advanced instruments, including sweep, plane cut, bend, shear, and inset. Modeling is performed by selecting and modifying different aspects of a model's geometry. Then users can add textures and materials to their models, to make their designs more detailed.
Wings’ AutoUV facility, that allows to export an unfolded image of your model’s surface for painting and texturing is worth mentioning as well.
The majority of popular CAD software application nowadays are based around interactive graphical user interface. Take for example BLR-CAD, LibreCAD or QCAD, where you create 3D models by using construction tools, adding blocks and navigating layers.
Antimony however takes a completely different approach to parametric 3D modeling. The app is developed around the concept of graph composition. In the program, 3D object is broken down into individual shapes and primitives, boolean and math operations, and other various transformations. By joining and subtracting these components, users are enabled to design complex functional objects. Each component is represented by a node, which can be connected by noodles.
In addition to node-based modeling, Antimony provides a handy 3D view window. There you can modify, move and scale objects, and the data in the corresponding nodes will be updated automatically.
Finished models can be exported into height maps for 2.5D projects, as well as converted into STL file format for further 3D printing.

When approved, the best elements than can be incorporated into one master design without any hassle - another extremely useful feature of the program.
This program is unlike most new-day CAD programs that allow you to create and edit 3D using explicit modeling method. Instead, OpenSCAD goes beyond interactive modeling straight into coding and focuses on CAD aspects of the modeling process rather than artistic ones.
This free software is more of a 3D compiler, which is based on two main principles, specifically constructive solid geometry (CSG) and extrusion of 2D outlines. OpenSCAD uses a detailed script file that describes the object to create models. An OpenSCAD document defines the dimensions and characteristics of an object, and describes all the modifications and alterations these objects undergo, to make a perfectly precise text-to-model rendering.
Though you may lack the feeling of total control over your design, which you get while working with an interactive CAD software, using code for 3D modeling gives you other perks. This approach makes it possible to easily change any step in the modelling process, make designs with easily-changeable parameters, or reuse pieces of code for other projects.
