Example Embodiment

[0034] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0035] In the design of automobile structure, CATIA software is usually used to complete it. Taking the front-shaped hood profile of the automobile design as an example, after the accessory layout and section design are completed, the initial structural design is carried out. Buffer block profile, strut installation, glue point and other de...

Abstract

The invention relates to the technical field of sheet metal processing, and discloses a CATIA-based vehicle sheet metal drawing method and electronic equipment, and the method comprises the following steps: newly building a first model, a second model and a third model in CATIA software; generating a first surface patch structure on the basis of the section elements in the first model; in the second model, a solid model is generated with the first patch structure as a basic plane, chamfering operation is conducted on the solid model, and a second patch structure with a fillet is generated; and in the third model, establishing a geometric figure set of the environmental part by taking the second patch structure as a basic plane. The technical scheme provided by the invention has the beneficial effects that the data of the first model, the second model and the third model adopt the link relationship, so that the error reporting rate is reduced, the modification and updating efficiency is improved, the visual degree is improved, and searching and updating are facilitated. And by modifying section elements to drive part design, the interference problem is avoided.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a CATIA-based vehicle sheet metal drawing method and electronic equipment. Background technique [0002] Generally speaking, the general process of automobile design is to provide the external modeling surface. The engineers arrange the vehicle accessories according to the modeling surface, and then carry out the section design work. After the section design is completed, the structural design is carried out. During the structural design process, it is necessary to cooperate with The process and surrounding environment parts are discussed, and the analysis results of CAE also need to be met. By continuously modifying the data to meet the final structure, process and performance, etc., the drawings are released, and the next step of manufacturing is carried out. [0003] Drawing of the sheet metal parts of the inner panel of the hood, the GSD module in CATIA is gene...
