LibreCad - свободная САПР для 2D черчения и проектирования

LibreCad - кроссплатформенные и свободная САПР (система автомитизированного проектирования) для 2-х мерного черчения и проектирования, созданная на основе QCad. Предназначена для создания чертежей, конструкторской и технологической документации. Работает под управлением операционных систем Linux, Windows и Mac OS X. Распространяется под лицензией GNU General Public License. Программный код написан на языке программирования С ++ и с использованием библиотек Qt4. Сначала проект назывался CADuntu, но это название многим не нравилась (в частности потому, что была похожа на название Ubuntu и звучало так, словно это специальный дистрибутив Linux для инженеров, на основе Ubuntu Linux). Поэтому, в декабре 2010 г. CADuntu переименовали в LibreCAD. Функционально LibreCAD соответствует оригиналу, но заметно улучшена работа с юникодом, в частности, корректно сохраняются надписи и названия слоёв. Может служить альтернативой коммерческому AutoCAD.

Разработчик: LibreCAD Team
Лицензия: Free (Open Source)
