Top 17 Best Free and Open-source CAD Software 2022

CAD—computer-aided design or computer-aided drafting—is a technique that allows you to build real-world items on your computer screen in order to better comprehend them. For example, if you want to create something new and innovative, such as a new home, automobile, bridge, or other structure, you should be able to view it before putting it into action in the actual world. You’re curious about how it looks and functions.

CAD technology is widely employed in a variety of engineering design domains. The development and deployment of CAD systems has resulted in significant changes in traditional product design methodologies and production models, with enormous societal and economic advantages.

Computer-aided conceptual design, computer-supported collaborative design, huge information storage, administration, and retrieval, design method research and associated concerns, and support for innovative design are now research hotspots in CAD technology.
It is expected that technology will advance, resulting in a design modification.

CAD technology is continually evolving and expanding. The use of CAD technology has helped to improve corporate design efficiency by optimising design schemes, lowering technician labour intensity, shortening design cycles, and increasing design uniformity.

More and more people are realising the value of CAD in increasing production. CAD technology is widely utilised in the industrial, electronics, aerospace, chemical, and construction sectors, among others.

Parallel design, collaborative design, intelligent design, virtual design, agile design, and whole lifecycle design are examples of design methodologies used in current product design patterns. CAD technology is bound to evolve in the direction of integration, intelligence, and synergy as artificial intelligence, multimedia, virtual reality, information, and other technologies advance. Enterprise CAD and CIMS technologies must be implemented in stages, with e-commerce as the ultimate aim.

Realize integrated, intelligent, and networked management from inside the organisation, leverage e-commerce to bridge corporate boundaries, and really realise the agile supply chain between customers, companies, and suppliers.

List of the Best Opensource and Free CAD Software

Here are several 3d cad software free options, including opensource, that are ideal for getting started with designing and 3D modelling for both beginners and pros…

1. Archimedes

Archimedes is a free and open-source software-aided design (CAD) programme (Computer-Aided Design). Blender is a free and open-source 3D creation suite that supports rendering, compositing, and motion tracking, as well as video editing and game creation. It can be used for modelling, rigging, animation, simulation, rendering, compositing, and motion tracking, as well as video editing and game creation.

2. Blender

Blender is free and open-source 3d cad software free that includes a 3D creative package that supports modelling, rigging, animation, simulation, rendering, compositing, and motion tracking, as well as video editing and game production. See also: Downloading and Installing Blender on Ubuntu.

3. SketchUp: 3D modelling for everyone

SketchUp is a free online 3D modelling software that may be used to create lines and forms.
Surfaces may be pushed and pulled to become 3D shapes. Stretch, copy, rotate and paint to create whatever you want.

4. LibreCAD

LibreCAD is a free Open Source 2D CAD tool that runs on Windows, Mac OS X, and Linux.
LibraCAD is a branch of QCAD, and its interface is similar to that of AutoCAD. So, if you’re comfortable with AutoCAD, you’ll have no trouble using LibraCAD. It only supports 2D, so if you’re looking for open-source 3d cad software freeto create a site plan or something flat, this is the way to go.

5. OpenSCAD: 3D CAD Modeller

Another 3d cad software free worth mentioning is OpenSCAD, which is available for Linux/UNIX, MS Windows, and Mac OS X. OpenSCAD has two primary modelling techniques: The first is constructive solid geometry (also known as CSG), and the second is an extrusion of 2D outlines. OpenSCAD can read and produce 3D models in the STL and OFF file formats in addition to DXF files.

6. FreeCAD

It is yet another well-known open-source parametric 3D CAD modeller for CAD, MCAD, CAx, CAE, and PLM. It may be utilised by a wide range of people, including architects and engineers.

FreeCAD is built on the sophisticated geometry engine OpenCasCade and provides the same user interface on Windows, Mac OSX, and Linux platforms. It supports a wide range of open file formats, including STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE, and many others.

7. QCAD – 2D CAD

QCAD is a free and open-source computer-aided drafting tool (CAD). It is a 2D design software used to create 2D drawings such as architectural plans, interiors, mechanical parts, and schematics and diagrams. QCAD is compatible with Windows, macOS, and Linux.


BRL-CAD is free and open-source 3d cad software free that runs on several platforms. It is a solid geometry and modelling system that contains an interactive geometry editor, ray-tracing for rendering and geometric analysis, network distributed frame buffer support, image and signal processing capabilities, and more.
