A method to realize automatic transformation of dwg three-dimensional model into x three-dimensional model

Abstract

The invention discloses a method for automatically converting a DWG three-dimensional model into an X three-dimensional model, and belongs to the technical field of engineering design. The method includes the following steps: (1) Data analysis: traversing the DWG three-dimensional model to obtain the geometric information, texture and texture of each entity of the model; (2) Geometric information processing: traversing the entity geometric information obtained in step (1), according to X 3D model format requirements are processed and entity indexes are created; (3) Texture and texture processing: process the texture and texture information obtained in step (1); (4) X 3D model format output: will pass through step (2) ) The geometric information of the processed model entity is written into the X 3D model file according to the entity index; (5) Material library output: write the texture and map processed in step (3) according to the entity index created in step (2) into the X 3D model file. The invention enables the three-dimensional design results to be completed once and utilized for multiple times.

Description

technical field [0001] The invention is applicable to the technical field of engineering design, and specifically relates to a method for converting a DWG three-dimensional model designed and produced by an AutoDESK series platform into an X three-dimensional model. Background technique [0002] At present, in the field of 3D engineering design, the results of 3D design models produced by different design platforms have poor versatility, and the same platform basically does not support the results produced by other platforms. Even if some formats support manual conversion, the model effect after conversion is still the same. It is greatly discounted, which hinders the reuse of 3D design results in different platforms, reduces work efficiency, and increases design costs. [0003] The DWG 3D model format produced by Autodesk's series of 3D design software is a relatively common design model format in the industry. In actual production work, it is often necessary to place it on...
