Abstract

The invention provides a three-dimensional rapid modeling system and method based on a building two-dimensional CAD drawing. The system comprises a standardized preprocessing function module, an effective point line information rapid extraction module, a building classification component model modeling module and a building integrated modeling module. Performing standardized preprocessing according to the building two-dimensional CAD drawing to form standardized basic data; Merging the vector points and the vector lines which are overlapped or are very close to each other in the basic layer; carrying out quick extraction of effective point line information; rapidly constructing a building classification component model; obtaining a corresponding building integrated three-dimensional modelaccording to the requirements of professional application.The invention discloses an application of three-dimensional building model modeling based on a building two-dimensional CAD drawing. The technical method, system and application for achieving three-dimensional rapid modeling based on the building two-dimensional CAD drawing by fully utilizing the spatial logic relation between the buildingtwo-dimensional drawing and the three-dimensional structure overcome the defects that an existing human-computer interaction three-dimensional modeling technology is low in modeling speed, prone to errors and the like.

Description

technical field [0001] The invention relates to the technical field of CAD modeling, in particular to a three-dimensional rapid modeling system and method based on two-dimensional CAD drawings of buildings. Background technique [0002] The national and local governments have issued a series of relevant guiding policies for building information modeling (BIM), coupled with the development of housing industrialization, there is a huge demand space for the development and application of 3D architectural modeling technology. However, when the traditional human-computer interaction mode is used to model the 3D architectural model based on the architectural 2D CAD drawings, the modeling efficiency is low, and it is easy to cause the 3D architectural model results to be inconsistent with the architectural 2D CAD due to human errors in modeling operations. Drawing information and other defects. Contents of the invention [0003] The aim of the present invention is to solve at le...
