Dear Unity Community, I'm very interested in building a game that allows the users to design buildings. In order to do this, I need to somehow implement some basic CAD functionality into the game. For example, users must be able to work at a scale, draft basic 2D building plans, then extrude the walls, build floors, place windows, change exterior materials and designs. I'm diving into the research now, but from my understanding, unity seems like it general is used to import geometry from outside modelling programs. Is there any references, resources or precedent projects which achieve the basic CAD functionality I talk about that you could share? Thanks so much!
