2D and 3D buildings modeling by geodetic measurements data

Abstract

Many inventors and companies still use 2D drawings and are starting to realize a 3D design because 3D modeling can save time and money. The objective of the research is to sift advantages and disadvantages of 2D and 3D modeling using AutoCAD, Autodesk Revit Architecture and Autodesk Revit MEP software, and to compare BIM and CAD technologies. For the research was measured second floor of Vilnius Gediminas Technical University and was drawn 3Dmodel. The results of the research indicate that popular AutoCAD software with 2D modeling is universal, it is good to learn to draw, to do small-scale projects. But Building Information Modeling lets for us not just to do, but to create and to model projects. The goal of BIM is to control calculations and interaction of elements for software system, because it is more quick, more accurate and easier for us.
