10 Best Free CAD Software for creating 2D technical drawing and 3D projects

CAD Design

All architects and engineers know the value of an impressive design which is not possible to draw without using CAD.

But most of the CAD programs are highly paid and because of this, we take our step back even before downloading it.

If you need to work or learn how to use a CAD program, without spending too much money on a professional program like Autocad or others, you can use one of these free programs that provide all the functions of a CAD program.

Here is a list of the top 10 free programs to download for Windows PC, Mac and Linux for technical drawing in both 2D and 3D projects.

10 Free CAD Programs for 2D technical drawing and 3D projects

FreeCAD

Free CAD is an open source program for Windows, Mac and Linux that directly addresses the engineering and design of products for mechanical use.

It can also be used for architectural projects or other engineering sectors based on 3D modeling.
Although free, FreeCAD is considered as an alternate of other popular CAD programs thanks to its ability to create real 3D solids, support for networks, 2D drawing and many other professional features. The program is modular therefore expandable with many extensions.

NanoCAD

NanoCAD is one of the best free and unlimited solutions for creating 3D CAD drawings.
Its most important feature is the native support to the DWG format which is then that of Autocad.

This means that a DWG file created with nanoCAD can be sent to other people who can then open it with Autocad without having need to convert.

Sculptris

Sculptris is a free 3D graphic design program for Windows and Mac.
Easy to use, it’s not really a technical drawing program, but a software to draw 3D models like sculptures or figures.

As the name of this little software recalls, it serves to create virtual sculptures.In practical terms, it means that with Sculptris you can draw three-dimensional figures but not animations as you can do with the more complicated Blender.

SketchUp

SketchUp is one of the most popular 3D modeling programs used primarily for architectural works and other niches in the 3D project industry.

The program for Windows and Mac is complete and professional with all the tools included for free. You can also see the galleries of works done to understand that there are no limits of using this program.

LibreCAD

LibreCAD is a free, open source CAD drawing program for Windows, Mac and Linux.

A complete tool that is proposed as an alternative to Autocad. LibreCAD can be used for all 2D architectural engineering drawings, to design mechanical parts, for construction, simulation, interior design, creative design and diagramming.

DraftSight

DraftSight is another free 2D CAD editor for professional CAD users, students and teachers, to work on DWG files.

The program can appeal to those who prefer minimal and simple CAD software. DraftSight can be downloaded for Windows, Mac and Linux.

OpenSCAD

OpenSCAD is a 3D modeling platform ideal for engineers, to design parts of machines using script programming. So there is no button interface and it is only for programmers.

Kicad

KiCAD is a free design tool for drawing printed circuit boards (PCBs), for Windows, Mac and Linux.

QCAD

QCAD is available for all computers to create technical drawings of buildings, mechanical parts or even diagrams and diagrams.

Since it is open source, QCAD is modular and extensible.Its 2D CAD platform is powerful yet easy to use even for a beginner who has little or no experience.

3DCrafter

3DCrafter is a simple 3D modeling program that works simply through drag and drop. It is used to create animated models by drawing scenes in real time.

I'm a fan of the world of video games for PCs since childhood, from the days of games on Floppy Disk and the last glories of the Commodore, reading magazines such as PC Gamer, Games For My Computer and many others. Even the other platforms intrigue me, but the first love never forgets.
