    Not your usual Architectural Modeler

    Why do Archicad and Revit only share 30 or 40% of the global architectural sofware market ? Maybe because lots of small practices find these software unadapted to the way they work, and to their bank account. I think there's place for an open software that doesn't work like the existing. It will be simple in its tools and processes, and will have infinite capabilities. This will be possible by defining a logical structure. As I am an architect, and I know very little about programming, and wouldn't reach even in 10 years the necessary level to be able to write anything useful for this type of software, my part will be to bring ideas and coherence to this project. If you want to know some more : - go to the blog https://sourceforge.net/p/mollino/blog/ - write me a message ;) I speak french, german, english and italian. Martin Lucas
