The course aims at providing students with advanced skill in architectural survey and 2D/3D digital modelling. Digital models are the fundamental tool through which the engineer, who works in the field of building constructions and environmental systems, can understand, analyse, and design architecture. Digital Modeling for Architecture gives a theoretic basis to understand the difference between a wide range of heterogeneous digital models together with applicative tools and strategies to build and manage them in a 3D digital environment. The course is structured in three main parts. The first one is related to architectural survey. Students will deal with the concept of metric accuracy a will have an overview on different survey methods and techniques. In this unit students will work with 3D point clouds coming from different sources to extract 2D and 3D models. The second part is related to the study of the mathematic modelling approach to control shapes and geometries for the construction of the 3D digital model. The third part is devoted to illustrating Building Information Modelling (BIM) principles applied to architecture to define complex information systems.
