6 Free Open-Source Architectural CAD Software

Updated on August 8, 2019 in Software 2019

Setting up an architecture or interior firm is a dream come true for most of us, but the draw back would be buying new workstations. It is not the hardware part that burns a hole in most of the bosses pocket, its the software. I hate to admit this but I believe most of the architecture firm in the developing world uses pirated version of every CAD software available on the market, its a risk that most asian bosses are willing to gamble. PushPullBar has this forum on open source software that I think future bosses would find it useful. If you can’t afford the original, then go for open-source.
