Abstract

The invention discloses a method for head contour modeling based on a CATIA (Computer-graphics Aided Three-dimensional Interactive Application) knowledge project template. The method comprises the following steps: firstly, creating a head contour template, designing the input information of the head contour template, and determining the output information of the head contour template; secondly, setting up the invocation environment of the head contour template, and determining the input condition of the head contour template before invocation; thirdly, invocating the head contour file template, and modifying and confirming the parameter information of the head contour file; and fourthly, achieving product design check. The modeling method disclosed by the invention integrates the best head contour modeling method, so that the design process of the head contour product is free from repeated product modeling and assembly work, and the head contour template can be invocated directly; and the head contour template has much built-in head contour design knowledge, and can perform automatic knowledge check and perform self-adaption update, so that automatic prompt is sent if the knowledge content is exceeded.

Description

technical field [0001] The invention belongs to the technical field of automobiles, relates to the modeling technology of automobile parts, and in particular designs a head envelope modeling method. Background technique [0002] At present, CAD technology has been widely used in mechanical product design. Existing CATIA, PRO / E, UG and other software are based on the theory of parameter-driven and provide a strong parametric design function. Based on the parametric function, some modeling processes can be packaged and packaged through appropriate secondary development, so as to realize template-based modeling, which can improve efficiency and modeling quality. The traditional head envelope modeling method is to model, assemble, and then check and modify interference for each product. Step by step, the time period is long, and the product models arranged on different models or different seats of the same model have poor versatility, and often need to be redesigned, and the a...
