LibreCad,是一個能執行在Windows、MAC、Linux上的自由的開源個人CAD應用程式。原先是QCad社群版的一個分支。
優點
[編輯]- 自由軟件:不用再為特許條款費用擔憂。
- 無語言障礙:支援眾多的語言版本,使得LibreCad用戶沒有語言障礙。
- GPLv2公共授權:你可以使用LibreCad,改進LibreCad,複製分發給別人,並且免費獲得來自全世界的LibreCad用戶的支援和LibreCad開發者的支援。
- 開源社群專案:LibreCad是一個開源社群專案,LibreCad開發者不斷吸納新的技術和想法,LibreCad的未來的決定權在每次的投票,你也可以決定LibreCad的未來。
歷史
[編輯]2010年前後,QCAD 社群版v2.0.5.0分支開始了獨立開發,形成了現在的LibreCAD。最早的用戶介面是基於Qt3圖形庫的。
現在LibreCAD的圖形介面基於Qt5,因此它可以在多個平台上執行並保持相同的介面。[2][3]
GNU LibreDWG庫是在GPLv3特許條款下釋出的,它不能用在以GPLv2特許條款釋出的LibreCAD(和FreeCAD)上。[4][5]因為它們的特許條款不相容。[6]有人向FSF提出將GNULibreDWG重新特許為GPLv2,但遭到了拒絕。[7]最後通過重寫一個以GPLv2釋出的稱為libdxfrw的替代庫才解決了這個問題,[8]新庫具有更完整的DWG支援。

[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."

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. The programs have dependencies on the popular GPLv2 license while the Free Software Foundation will only let LibreDWG be licensed for GPLv3 use, not GPLv2.

[...]the unfortunate situation with support for DWG files in free CAD software via LibreDWG. We feel, by now it ought to be closed. We have the final answer from FSF. [...] "We are not going to change the license."
