LibreCAD

Around 2010, the QCAD Community Edition 2.0.5 was forked to start the development of what is now known as LibreCAD. Originally, the GUI was based on Qt3 libraries.{{cite web |title=LibreCAD the only major free Computer Aided Design program |url=http://www.soft32.com/blog/platforms/windows/librecad-the-only-major-free-computer-aided-design-program/ |accessdate=20 January 2013}}{{cite web |last=Dube |first=Ryan |date=2 March 2012 |title=6 Tips To Get The Most Out of LibreCAD Free CAD Software |url=http://www.makeuseof.com/tag/5-tips-librecad-free-cad-software/ |accessdate=20 January 2013}}

CADuntu — was the initial QCAD CE fork project name. It was used for a short time and, after discussion with users, has been replaced by LibreCAD, as to not be associated with Ubuntu and Canonical Ltd.

The main feature of LibreCAD 1 was porting of its graphical user interface (GUI) code to Qt4, so it can run identically on several platforms.{{cite web |last=Wallen |first=Jack |date=27 January 2012 |title=DIY: LibreCAD offers basic CAD tools for free |url=http://www.techrepublic.com/blog/doityourself-it-guy/diy-librecad-offers-basic-cad-tools-for-free/1306 |accessdate=20 January 2013}}{{cite web |title=Review about Linux LibreCAD and Linux Inkscape |url=http://newsoftwarepc.com/review-about-linux-librecad-and-linux-inkscape.html |url-status=usurped |archiveurl=https://web.archive.org/web/20121120014147/http://newsoftwarepc.com/review-about-linux-librecad-and-linux-inkscape.html |archivedate=20 November 2012 |accessdate=20 January 2013}}

LibreCAD 2 implements Qt5 and Qt6 library support.

As of 2024, LibreCAD development split into two branches:

• 2.2.1.x — actual release with bug-fix updates;
• 2.2.2_alpha — alpha version of the future release, with many new experimental feature, not for regular use yet.

File:LibreCAD 3 screenshot.png

LibreCAD 3 — is an experimental fully rewritten from scratch LibreCAD version, designed to be GPLv3 compatible with LibreDWG, with Lua-scripting, Ribbon UI.

Development mostly done during 2018–2023 GSoC sessions, in the collaboration with BRL-CAD team.

Latest commits and test builds built in September 2023, and since development stalled. LibreCAD team is actually frozen this project, and are focusing on LibreCAD 2 and libdxfrw library development.

Version history data are taken from official Web site, project pages on Sourceforge and GitHub.

LibreCAD is available in over 60 languages.{{Cite web |title=LibreCAD – Free Open Source 2D CAD |url=https://librecad.org/translate.html |access-date=2024-08-22 |website=librecad.org}}

It uses the AutoCAD DXF file format internally for import and save files, as well as allowing export to many other file formats.

As of version 2.2.0, LibreCAD is capable of reading and writing the following file formats:

Open File or Import Block

• CAD: DXF, DWG, {{ill|Jw_cad|lt=JWW|ja|Jw_cad}}, Shapefile (deprecated)
• CAD font: LFF, CXF

Import Image

• Vector image: SVG, SVGZ
• Bitmap image: BMP, CUR, GIF, ICNS, ICO, JPEG, JPG, PBM, PGM, PNG, PPM, TGA, TIF, TIFF, WBMP, WebP, XBM, XPM

Save File

• CAD: DXF (2007), DXF (2004), DXF (2000), DXF (R14), DXF (R12)
• CAD font: LFF, CXF

Export

• PDF (or sent drawing to printer for direct print)
• Vector image: SVG, CAM (Plain SVG)
• Bitmap image: BMP, CUR, ICNS, ICO, JPG, PBM, PGM, PNG, PPM, TIF, WBMP, WEBP, XBM, XPM

As the GNU LibreDWG library is released under GPLv3, it cannot be used by GPLv2-licensed LibreCAD and FreeCAD,{{cite web |last=Prokoudine |first=Alexandre |date=26 January 2012 |title=What's up with DWG adoption in free software? |url=https://librearts.org/2012/01/whats-up-with-dwg-adoption-in-free-software/ |accessdate=12 April 2025 |publisher=librearts.org |quote=[Assimp's Alexander Gessler:] "Personally, I'm extremely unhappy with their [LibreDWG's — LGW] GPL licensing. It prohibits its use in Assimp and for many other applications as well. I don't like dogmatic ideologies, and freeing software by force (as GPL/GNU does) is something I dislike in particular. It's fine for applications, because it doesn't hurt at this point, but, in my opinion, not for libraries that are designed to be used as freely as possible." [Blender's Toni Roosendaal:] "Blender is also still "GPLv2 or later". For the time being we stick to that, moving to GPL 3 has no evident benefits I know of. My advice for LibreDWG: if you make a library, choosing a widely compatible license (MIT, BSD, or LGPL) is a very positive choice."}}{{cite web |last=Larabel |first=Michael |date=24 January 2013 |title=FSF Wastes Away Another "High Priority" Project |url=https://www.phoronix.com/scan.php?page=news_item&px=MTI4Mjc |url-status=dead |archiveurl=https://web.archive.org/web/20161109200145/https://www.phoronix.com/scan.php?page=news_item&px=MTI4Mjc |archivedate=2016-11-09 |accessdate=2013-08-22 |publisher=Phoronix |quote=Both LibreCAD and FreeCAD both want to use LibreDWG and have patches available for supporting the DWG file format library, but can't integrate them.

Due to copyright issues with QCAD CE's fonts in CXF format, initially used in LibreCAD, it was decided to create own font format.

LibreCAD Font Format — is a plain text file fomat (with *.lff file extension) for single stroke vector fonts.{{Cite web |title=LFF Font Format |url=https://github.com/LibreCAD/LibreCAD/wiki/LFF-Font-Format |access-date=2024-08-22 |website=GitHub |language=en}}

There is a way to edit LFF fonts directly in LibreCAD or create fonts from fonts in other formats. Converters to LFF format are designed for the next formats:

• TTF (TrueType fonts) — converter available online on official site and as a CLI utility;{{Cite web |title=LibreCAD – Font Converter |url=https://librecad.org/ttf2lff/ |access-date=2024-08-22 |website=librecad.org}}
• JHF (Hershey fonts) — converter implemented as CLI utility;
• Shx (Shapefile Index fonts) — converter designed by 3rd party developer.

LibreCAD Font Format adopted in SolveSpace CAD, and LibrePCB software designed FontoBene (*.bene) font format for PCB, which is derived from LFF.

LibreCAD is in use in many countries for educational purposes at schools and universities, in production at firms and factories for design and manufacturing various items, architecture design, garden and landscape design, etc.{{Cite web|url=https://ouci.dntb.gov.ua/en/works/leyzq0gl/|title=Development of Computer Skills to Draw in the LibreCad from Virtual Learning Environments|website=ouci.dntb.gov.ua|language=uk-UA|access-date=2024-08-15}}{{Cite web|url=https://orchowski.eu/gallery/projekty-techniczne/|title=Projekty techniczne|website=naturaprojekt.pl|language=pl-PL|access-date=2024-08-17}}{{Cite web|url=https://normanhurb-h.schools.nsw.gov.au/learning-at-our-school/digital-devices--bring-your-own-.html|title=Digital devices (bring your own) – Normanhurst Boys High School|website=normanhurb-h.schools.nsw.gov.au|access-date=2024-08-17}}{{Cite web|url=https://researchguides.gonzaga.edu/engineering/toolkits|title=LibGuides: Engineering & Applied Science Research Guide: Online Platforms and Toolkits|last=Gustavsen|first=Nicole|website=researchguides.gonzaga.edu|language=en|access-date=2024-08-17}}{{Cite web|url=https://uwm.edu/data-science/discipline/architecture/|title=Architecture Archives|website=Data Science at UWM|language=en-US|access-date=2024-08-17}}

Due to free licensing, in some countries LibreCAD is used for decreasing budget expenses on software licensing by replacing commercial CAD at state and governmental organizations, public schools, etc. Also, LibreCAD is chosen in cases where there are no reachable official dealers of commercial software, or all available commercial CAD solutions are too expensive.

In some countries LibreCAD is used to circumvent international sanctions; for example, in Russia it has been used in light of international sanctions implemented in response to the invasion of Ukraine.{{Cite web|url=https://www.it-world.ru/tech/choice/185175.html|title=САПР-замещение: что использовать вместо AutoCAD?|date=9 June 2022|website=ИТ Медиа {{!}} Продукты и технологии|language=ru|access-date=2024-08-17}}{{Cite web|url=https://www.cnews.ru/news/top/2024-07-18_rossijskie_vuzy_hotyat_prinuditelno|title=В российских вузах хотят запретить AutoCAD – CNews|website=CNews.ru|language=ru|access-date=2024-08-17}}{{Cite web|url=https://habr.com/ru/articles/425161/|title=Обзор бесплатных 2D САПР|date=10 October 2018|website=Хабр|language=ru|access-date=2024-08-17}}{{Cite web|url=https://habr.com/en/articles/446576/|title=Импортозамещение, или как «Вертолеты России» сделали что-то не так|date=3 April 2019|website=Habr|language=en|access-date=2024-08-17}}{{Cite web|url=https://habr.com/en/news/706218/|title=После шести лет разработки вышла новая стабильная версия свободного 2D САПР LibreCAD — 2.2.0|date=18 December 2022|website=Habr|language=en|access-date=2024-08-17}}{{Cite web|url=https://bim-portal.ru/stati/chem-zamenit-autocad-alternativnyye-sapr/|title=Чем заменить AutoCAD?
