Problems solved by technology

[0002] During the design process of medium and heavy-duty trucks, manufacturing R&D companies mainly use two-dimensional drawings for the design of tube bundle assemblies and manufacturing of main pipe bundle assemblies. Estimate, the estimated size is not accurate, and the size of the two-dimensional map generated by the existing technology can be changed randomly, error-prone, and the verification period is long
[0003] In addition, the 3D design drawing of the tube bundle assembly is not related to the 2D drawing of the tube bundle assembly, and the 3D design drawing cannot be converted into a 2D drawing and cannot be used in actual production

Abstract

The invention discloses a tube bundle two-dimensional rapid drawing method and system based on full three-dimensional design and a storage medium. The method comprises the steps: creating a global flattening model for converting a tube bundle assembly three-dimensional design drawing into a two-dimensional drawing; automatically flattening the tube bundle assembly based on a global flattening model, and obtaining a tube bundle assembly two-dimensional graph mode; setting tube bundle size coordinates; creating an engineering drawing table; creating an engineering drawing assembly drawing; marking key size parameters and technical parameters of the tube bundle, and generating a tube bundle two-dimensional diagram; according to the drawing method, on the basis of design of the full-three-dimensional tube bundle assembly, two-dimensional accurate and rapid drawing of the tube bundle is achieved through automatic flattening of the tube bundle.

Description

technical field [0001] The invention belongs to the technical field of vehicle component design drawing, and in particular relates to a method, system and storage medium for two-dimensional fast drawing of a tube bundle based on full three-dimensional design. Background technique [0002] During the design process of medium and heavy-duty trucks, manufacturing R&D companies mainly use two-dimensional drawings for the design of tube bundle assemblies and manufacturing of main pipe bundle assemblies. The estimated size is not accurate, and the size of the two-dimensional map generated by the existing technology can be changed randomly, which is error-prone and has a long verification cycle. [0003] In addition, the 3D design drawing of the tube bundle assembly is not related to the 2D drawing of the tube bundle assembly, and the 3D design drawing cannot be converted into a 2D drawing and cannot be used in actual production. Contents of the invention [0004] Aiming at the ...
