Abstract

The invention discloses a BIM-based three-dimensional-building-model processing method and device. A three-dimensional building model generated on the basis of BIM is acquired; the three-dimensional building model is transformed into a two-dimensional planar model, and a region mesh layer corresponding to each component is generated; the region mesh layer is acquired, and a method of geometric surrounding is adopted to split the two-dimensional planar model into a two-dimensional model corresponding to each single component; and carrying out size labeling on the two-dimensional model corresponding to each single component according to a preset labeling rule to generate a component two-dimensional-model file with labeling information. Therefore, according to the BIM-based three-dimensional-building-model processing method and device provided by the invention, two-dimensional transformation and splitting are carried out on the three-dimensional building model on the basis of a BIM platform, a two-dimensional graph of each single component after splitting can be automatically generated by a three-dimensional graph of all the components, size labeling can be automatically carried out for the two-dimensional graph to facilitate use of subsequent production and machining links on the component, and efficiency of BIM fabricated-building technology is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a BIM-based three-dimensional building model processing method and device. Background technique [0002] The biggest difference between prefabricated buildings and traditional buildings lies in the way houses are built. Traditional buildings generally use cast-in-place methods. That is to say, take the wall panel as an example, support the formwork on site, and then pour flowing concrete into the space formed by the formwork. After the concrete solidifies to a certain strength, the formwork is removed to form a wall. The disadvantage of the cast-in-place method is that there are many wet operations on site, troublesome formwork support and removal process, large labor demand on site, chaotic management, waste of water, high dust, high noise, long construction period, uncontrollable construction quality, and prone to on-site accidents. Cut corners or due to lack o...
