Qcad is an application for computer aided drafting (cad) in two dimensions (2d). with qcad you can create technical drawings such as plans for buildings, interiors, mechanical parts or schemas and diagrams.
I've learned CAD in this application. I've been using this for the last 3 years for my personal home drawings, commercial construction drawings, as well as combined sketch of several survey numbers of land. All in all, it is a very easy to learn and use 2D CAD application for home and land drawings. I'll recommend users to please use it for at least 2-3 months. It sort of grows on you. The functionality/MB and functionality/$ (come on, it's free) quotient is very high and could give any other FOSS or even commercial CAD application stiff competition. There is also a newer trial version available for download in the official website. It is a radically improved version. Try it out too! All in all, not much to lose but a lot to gain. Thumbs up for this app and 5 stars.
I like it but.....I think Programmers should make it more sourcefull and extensions supports.I am an Civil enginnere student. I need to use Autocad .ANd for only Autocad i have to go to windows.Please make it possible to support "DWG" formates.
