A PROCEDURE TO IMPORT A COMPLEX GEOMETRY MODEL OF A HERITAGE BUILDING INTO BIM FOR ADVANCED ARCHITECTURAL REPRESENTATIONS

Abstract. The aim of this communication is to present the advantages and disadvantages a Scan-to-BIM process applied heritage building in order obtain advanced technical drawings be used analysis illustration project. whole described includes: survey planification data acquisition with Terrestrial Laser Scanner; processing cleaning point cloud; 3D mathematical modelling; proposal for semi-automatic modelling organic elements; import final model into BIM environment. Rhinoceros (McNeel) Revit (Autodesk) are main programs used. crucial aspect workflow found at moment importing geometrical Revit, having accommodate criteria program terms tolerances, geometric structure solids, incompatibilities NURBS libraries, etc. result divided families subcategories where visual attributes can assigned per element, parameterized other information added (orthophotographs, wireframe drawings, etc.). In words, from which highly configurable representations (plans, vertical sections, perspectives, isometric exploded view, etc.) obtained generate analyses field Architectural Graphic Expression.
