Building Information Modeling (BIM) has become a mandatory standard in many countries. Perhaps the most innovative and important technology is the point cloud service to BIM which makes the renovation of old buildings easier and faster.
Historical and heritage structures are generally built according to complex, non-parametric calculations. 3D scanners and photogrammetry now allow the recording of physical spaces and non-regular calculations of structures. The realistic HBIM (BIM for historic buildings) is essential to model the building and coordinate the phases of conservation and renovation.
The use of scan to BIM and point clouds is an interesting technology for car renovation projects, it avoids the cost of manual measurements which are often approximate and inaccurate. Moreover, the digitization, conversion and transmission of physical asset data, although it deserves specific knowledge and skills, is faster and more accurate. HBIM modelers build a parametric library of components and models that will be used to model irregular structures of historical heritages from analyzes.
Revit families for carvings, irregular geometries, roofs and roof components, framing can be used to develop building structures and model them.
It is necessary to be able to identify and categorize the different geometric structures that make up historical heritage sites such as size, shapes, plans, curves, extrusions, etc. from raw digitization data and then model them using cross sections, Parametric Revit families and assigning them appropriate levels.
In addition to this, architectural, structural, and MEP models can have other components than architectural shapes and geometries. They can have MEP components such as conduits and valves and structural models such as columns, beams and bolts which must be integrated and included in the model as built.
