从QCAD、CADuntu到LibreCAD

QCAD当然可是大名鼎鼎的AutoCAD之开源Alternative，可惜后来被收购，商业版没市场，连带Community版本也是N久都没什么动静，人家QT都被Nokia买并LGPL好久了了，他老夫子居然还是QT3。

所以有好事者Ries van Twisk开始做QCAD的QT4 Porting，然后就有了CADuntu。当然，Open source，那是一脉相承,支持Windows、Mac和Linux。

----------------------------------------------------------------------------------------------

The project was started after Ries van Twisk, its initiator, decided to simplify his work by creating a CAM plug-in for community edition of QCad.

He soon figured out that creating something for an application based on an aging toolkit would lead him nowhere and thus started porting CADunutu to QT4 first.

----------------------------------------------------------------------------------------------

可CADuntu这个名字太丑了，所以在一次投票中LibreCAD以140：20票成为了它的新名字。2011年4月，还基于GNU libreDWG开始支持DWG。

呵呵，什么时候Piaoger也把这东西拖下来瞅瞅。
