Abstract

The embodiment of the invention discloses a method and a device for generating two-dimensional construction drawings based on a three-dimensional model of a civil structure, belonging to the technicalfield of computer graphics. The method comprises: 3-D model of civil structure is obtained, the three-dimensional model of civil structure is parsed into a predefined data structure as information data storage, the information data is imported into the drawing platform, the two-dimensional expression diagram is drawn according to the determined drawing range and the target object, and the determined target labeling information and the preset labeling information are labeled according to the preset labeling rules. Through adoption of the invention, user-defined symbols and legends can be adopted, labeling information can be automatically added, construction drawings that can be directly used can be automatically generated, and the drawings do not need to be adjusted and modified at a laterstage, that is, two-dimensional construction drawings that can be directly used can be generated by a three-dimensional model of a civil structure.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method and a device for generating a two-dimensional construction drawing based on a three-dimensional model of a civil structure. Background technique [0002] Factory 3D design management systems (PDMS, SP3D, etc.) have been widely used in engineering design and construction. [0003] Currently civil engineering professional modeling and painting Figure 1 Generally, the 3D model of the civil structure is established first, and the drawing module is used to project the 3D model into a 2D outline drawing, and then the technicians manually mark the dimensions and mark other information to form a 2D construction drawing. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Contour outline drawings are drawn by direct projection, which cannot identify and explain civil s...
