In the master's thesis a 3D-graphic model of a selected commercial building is presented, on the basis of which we present the possibility of registering the building in a 3D cadastre. For the purpose of understanding the problem of establishing a 3D cadastre, the legislation in the field of coordinate land cadastre and the building cadastre in Slovenia is presented. Further concepts of 3D modeling and type of 3D cadastre are defined, the advantages of the 3D cadastre are presented. The 3D wireframe model of the building was modeled with AutoCAD software environment based on data obtained from existing real-estate records, geodetic field survey data and project documentation of the building. The model was divided into several real estate units and the distribution of the building is graphically presented in several ways. In the discussion and conclusion of the thesis, findings about what data would be needed to facilitate the production of the 3D model and for the further establishment of the 3D cadastre in Slovenia, are presented.
