Hi,
My name is Danilo and I'm currently one of the directors of the National Federation of Architects <
http://www.fna.org.br/> in Brazil. As a federation of Trade Unions, we wish to boost the development of a free, open-source, CAD software for Brazilian Architects. We can provide official sponsorship and boost crowdfunding in our country and internationally -- since we are also supporters of the upcoming World Congress of the UIA (International Union of Architects) that will happen in Brazil next July. Brazil today has a huge community of more than 180.000 registered professionals.
LibreCAD would be an option for us! Can you please get in touch so we can move forward on this initiative?
