List of Free CAD Programs for technical drawing
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.
- In terms of drawing, the free software brings all the standard features you could expect from a true-blue CAD tool, like chamfering or sheet metal bending. However, in case you have no prior experience, use one of the handy design wizards to create flywheels, heatsinks, hex nuts, front panels, and more pre-designed parts.
- Computer aided design and drafting software is used not only in architecture and engineering, but also in the creation of video games and in the classroom. Due to the high demand of CAD, and the increased need for companies to invest in a CAD designer, computer aided drafting all together can cost an awful lot of money.
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 small 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 is perfect for those who prefer minimal and simple CAD software. DraftSight can be downloaded for Windows, Mac and Linux.
OpenSCAD

Mechanical Drawing software, free download
For an engineer or architect AutoCAD is essential, since it is the main work tool. But if you are still at university or have multiple computers to work on, you can very well install one of the programs recommended in this guide, so that we can still work on 2D technical drawings and 3D projects without spending much on the various AutoCAD licenses.
