Problems solved by technology

[0003] The former method uses parametric section lines to express the shape information of the process supplementary section well, but the straight line and arc cannot fully express the curve shape, and the curve shape between the section lines is not controlled; the latter method generates A large number of grid models can be directly applied to finite element analysis, but it is not convenient for secondary editing, and the number of updated grids is too large

Abstract

The invention discloses a method for creating and adjusting the process supplement based on a wire frame model, which is characterized by comprising the following steps of S1 creating a longitudinal line of the wire frame model; S2 establishing an end point matching relation of transverse lines between the section lines, and ensuring that the transverse lines are not intersected in the longitudinal direction; S3 creating a transverse line of the wire frame model; S4 performing local adjustment; S5 conducting the overall adjustment; S6 filling grids. Therefore, the shape is controllable and theadjustment is fast during the supplementary design of the automobile covering part technology.

Description

technical field [0001] The present invention relates to the field of computer-aided design of automotive panel process supplements, and more particularly, relates to a method of using wireframe models to create and edit automotive panel process supplements. Background technique [0002] In order to quickly create and conveniently edit the process supplementary surface of the automobile panel, the parametric process supplementary section line is usually established to control the section shape, and then the surface algorithm is used to generate the surface between the section lines, and the curve shape is updated by modifying the section line parameters during editing. In the article "Research on Parametric Design of Process Supplementary Surface and Binder Surface of Cover Part Drawing Die", it is proposed to create process supplementary surface through two-dimensional parametric section line. Arc radius control; "Mesh-based drawing model surface design method" proposes a me...
