The geometric fundamentals of design: towards a new descriptive geometry
, 2012 Geometry, thus directed towards the needs of the project, is the geometry that, bringing together millennia of experience, has been systematised by Gaspard Monge and that received from him the name of Descriptive Geometry (1794), and as such it is still ...
