- Ability to manage point clouds derived from acquisitions with fixed or mobile Laser Scanner systems or through digital photogrammetry techniques based on Structure from Motion algorithms. - Ability to use methods and techniques for automatic, semi-automatic and manual segmentation and classification of 3D point clouds for the subsequent parametric modeling. - Skills in the management of point clouds in BIM environment through Scan 2 BIM applications - Ability to understand the main criticalities of a BIM approach applied to the Cultural Heritage field - Ability to critically analyze the different scientific contributions available from the literature, analyzing the limits and potential of the different proposed solutions in the academic and professional field. - Ability to rework metric databases and convert them into BIM components, according to different workflows. - Ability to correctly define the information apparatuses that can be associated with BIM models and their parametric components.

Basic knowledge related to methods of representation encoded by descriptive geometry and architectural drawing and surveying will be considered acquired. Some bibliographic references related to basic geomatics for architectural modeling will be provided to fill any prior educational gaps.

The course is organized into 3 main knowledge fields. Each lesson will be characterised by the illustration of specific results from ongoing or already realised national and international research projects and case studies. Experts will also be invited to discuss specific topics. KNOWLEDGE OF METHODS - Introduction and main features of methods and tools for the acquisition and generation of 3D point clouds. - Introduction to point cloud-based reality modelling methods in the scan-to-BIM process. - Survey on the state of the art of BIM. Differences and similarities between CAD and BIM and between BIM and HBIM KNOWLEDGE OF TOOLS - 3D point cloud management: editing, segmentation and classification. Optimisation of point clouds for surface and object modelling and parameterisation. - Introduction to parametric modelling in the architectural field (graphical interface, templates, correlation between graphical, numerical and tabular information, customisation of existing libraries and creation of new libraries, etc.) and application to the assigned case study. - Communication of the project (enrichment with numeric and alphanumeric parameters, production of graphic outcomes). Plenary reviews of the assigned case study deliverables. IN-DEPTH CRITICAL ANALYSIS - Global versus local modelling. Management of point clouds in the BIM environment. Definitions of BIM and interoperability and research applied to real case studies. - BIM for building construction and management (HBIM): national and international research experiences.

The teaching activity will be divided into: KNOWLEDGE: theoretical lectures aimed at the acquisition of scientific skills and knowledge aimed at providing cultural and critical tools to students (about 30%-35%); KNOW-HOW: practical exercises aimed at the use of specific tools by students for the acquisition of methods and workflows proposed during the practical activities. These exercises will be essential for the testing of the deep and permanent understanding of the delivered contents (about 60%). The practical activities will be carried out in groups of a maximum of 3-4 students. REASONING: specific in-depth seminars may be organized (with the possible involvement of external experts from the academic and professional world) aimed at focusing attention on particular issues (about 5-10%); The evaluation is described for the assessment and grading criteria to take the exam.

The bibliography will be made available by the teachers during the course. It will be suggested the reading of articles published in conference proceedings or international journals available in open access, downloadable from the main repositories of scientific publishing websites.

Exam: Written test; Compulsory oral exam; Group graphic design project;

The exam aims to determine the individual knowledge of each student. To this purpose, the exam will be divided into two parts. A first theoretical part is aimed at assessing - by means of a written test with theoretical questions- the knowledge acquired during the course in relation to current legislation, the reference literature, the understanding of the main critical issues discussed during the course, as well as possible practical solutions. A list of theoretical questions will be made available to students. The second part of the exam refers to the outcomes of the group exercise during an oral discussion. The average length of the oral discussion is about 30 minutes. The graphic work produced in groups concerns the elaboration in a BIM environment of a case study that will be provided by the professors. The format used for the delivery of the exercise, the timing of delivery and the methods of in progress review will be discussed in the first lessons of the course. Evaluation Criteria. The weight of the theoretical part constitutes about 35% of the final evaluation. The remaining 65% refers to the value of the quality of the graphic work and its presentation. A prerequisite for passing the exam is to successfully pass both parts, written and oral. The final grade will be based on the clarity of the presentation, the property of language, the ability to synthesize and the active participation in the course activities.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
