Development of an autogeneration program for building a clear height cloud map based on BIM

Abstract

Because the clear height of a building involves many particularities of buildings, structures and equipment, the traditional design mode can only roughly estimate the clear height of a building and cannot fully reflect the distribution of the clear height of the whole building, which is not conducive to designers’ design and optimization of buildings. To solve this problem, the concept of a cloud map of the clear height of buildings was proposed for the first time. Based on Revit software, a BIM-based, automatic building clear height cloud map generation program, which realized the efficient analysis of BIM model clear height and can quickly obtain the building clear height cloud map, was developed, therefore enhancing the clear height analysis function of Revit. Compared with the traditional clear height area analysis color block diagram, the clear height cloud diagram of BIM was more accurate, which provides an effective technical means for designers to comprehensively evaluate the clear heights of buildings.
