Embodiment Construction

[0024] The design intent-driven natural language geometric modeling method of the present invention will be further described below with reference to the drawings and specific embodiments.

[0025] The implementation premise of the natural language geometric modeling method driven by the design intention of the present invention must have two prerequisites, one is to have a set of hardware system for implementing the present invention, and the other is to define a series of rules and establish a database in advance. In order to ensure that the above two prerequisites are used as prior art without affecting the implementation of the present invention, these two prerequisites are introduced below, and those of ordinary skill in the art should realize that through the following introduction, these two The prerequisites can already be implemented as prior art by those of ordinary skill in the art.

[0026] Implementation of the introduction of the hardware system of the present in...

Abstract

The invention relates to a design-idea-driven natural language geometric modeling method which comprises the following steps: step 1: design idea analysis: inputting a design idea in a natural language mode according to the design task by a designer, thereby forming a design idea file stored in the form of binary data; step 2: engineering semantic analysis: analyzing a binary statement in the design idea file, and carrying out mode matching operation on the binary statement and a preset binary field in an engineering database to form an engineering semantic file; step 3: automatic logical reasoning: transforming the engineering semantic data generated in the step 2 into predicate logic data and geometric model data according to a predicate logic transformation rule; and step 4: geometric modeling. The whole modeling process can be automatically completed by the system, thereby reducing the manual intervention and enhancing the modeling efficiency.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, and in particular relates to computer-aided geometric modeling technology. Background technique [0002] Advanced manufacturing technology is an important driving force for my country to realize the transformation from a "manufacturing country" to a "manufacturing power". Usually, the design process accounts for 60% to 70% of the entire product life cycle, and directly affects the production cost and cycle. At present, the product design process mostly follows the cyclic and iterative process of drafting a preliminary design plan → geometric modeling and analysis → revising the design plan → revising the geometric model until all design requirements are met. In this design pattern, the designer is in a very important position, which is mainly determined by the existing geometric modeling mechanism. The geometric model is an intuitive expression of the design scheme, an important...
