Building information modeling is now widely utilized in the building sector. Reverse engineering is evolving into a cutting-edge method for analyzing an object's structure, design, and functionality because of advancements in technology. This methodology allowed retrieving lost or nonexistent information on the construction by applying the most up-to-date approaches for obtaining spatial information about the object. The purpose of this research is to investigate the efficiency and application of conversion of a point cloud from an existing structure to a BIM model and subsequently checking interoperability to various FEM softwares using the IFC format. The primary focus of this research is on reverse engineering using data from three-dimensional scans, techniques for building three-dimensional models, and automation of this process using Python, Revit, and Revit plug-ins. Revit provides an interface for third-party plugins to interact with pointcloud and drawing objects in Revit. In the result of the research, several methods of modelling from the point cloud were identified, from manual to automatic one. This thesis represents the beginning of a path toward automating the creation of structural models using point clouds. This method improves BIM modeling procedures and will be helpful in the future. Building a structural model from a point cloud can be used to renovate or retrofit an existing structure. With this knowledge, the engineer can optimize workflow, improve model accuracy, and save time.
