LibreCad,是一个能运行在Windows、MAC、Linux上的自由的开源个人CAD应用程序。原先是QCad社群版的一個分支。

优點

  • 自由软件:不用再为许可证费用担忧。
  • 无语言障碍:支持众多的语言版本,使得LibreCad使用者没有语言障碍。
  • GPLv2公共授权:你可以使用LibreCad,改进LibreCad,复制分发给别人,并且免费获得来自全世界的LibreCad用户的支持和LibreCad开发者的支持。
  • 开源社区项目:LibreCad是一个开源社区项目,LibreCad开发者不断吸纳新的技术和想法,LibreCad的未来的决定权在每次的投票,你也可以决定LibreCad的未来。

历史

2010 年前后, QCAD 社区版 v2.0.5.0 分支 开始了独立开发,形成了现在的 LibreCAD。最早的用户界面是基于 Qt3 图形库的。

现在 LibreCAD 的 图形界面 基于 Qt5,因此它可以在多个 平台 上运行并保持相同的界面。[2][3]

GNU LibreDWG 库是在 GPLv3 许可证下发布的,它不能用在以 GPLv2 许可证发布的 LibreCAD(和 FreeCAD)上。[4][5] 因为它们的许可证 不兼容.[6] 有人向 FSF 提出将 GNU LibreDWG 重新许可 为 GPLv2,但遭到了拒绝。[7] 最后通过重写一个以 GPLv2 发布的称为 libdxfrw 的替代库才解决了这个问题,[8] 新库具有更完整的 DWG 支持。

[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."
