Mais uma alternativa ao AutoCAD trata-se do CADuntu. É uma cad 2d cara chapada do QCAD só que é código aberto e ainda se encontra em faze beta. Como o QCAD é multiplataforma facil de trabalhar.

For those of you who are trying to find a good alternative for AutoCAD, especially if the option is an open source software, it may become hard to find one that fits most of the needs of an architectural visualization artist. Due to the great number of options, it is always good to take a look at new options. This morning I just found another option that may be useful for architects. The tool is called CADuntu and is an open source CAD based on the community edition of QCAD.
