Abstract

The invention discloses a BIM-based method and device of automatic labeling of a two-dimensional graph. A three-dimensional building model generated on the basis of BIM is acquired; the three-dimensional building model is projected to generate the two-dimensional planar graph; and size labeling is carried out on the two-dimensional planar graph according to a preset labeling rule to generate a two-dimensional planar graph with labeling information. Therefore, according to the BIM-based method and device of automatic labeling of the two-dimensional graph provided by the invention, two-dimensional transformation is carried out on the three-dimensional building model on the basis of a BIM platform, the two-dimensional planar graph is automatically generated by a three-dimensional graph, sizelabeling is automatically carried out on the two-dimensional planar graph to facilitate use of subsequent production and machining links, 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 method and device for automatic labeling of two-dimensional drawings based on BIM. 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...
