AI Technical Summary

Technical Problem

Traditional methods cannot achieve multi-dimensional analysis of geometric features and semantic issues because existing technologies cannot effectively solve the multi-dimensional verification and rule adaptation of design specifications and semantic issues in 3D design models. This leads to deviations in the matching degree analysis of geometric constraints and semantic requirements in design specifications, making it difficult to fully cover the compliance verification needs of 3D design models.

Method used

The conformity analysis method for 3D design models based on large-scale language models establishes a multi-source data interaction channel through a product 3D scene collaborative review platform. It combines a product 3D semantic geometry collaborative verification algorithm, a spatial rule learning adaptation model, and a CAD point cloud feature encoding mapping model to achieve deep association processing between geometric topology data and semantic description information. This enables multi-dimensional verification and rule adaptation, generates a rule adaptation weight matrix and feature vector mapping relationship, and forms a comprehensive analysis dataset.

Benefits of technology

It enables multi-dimensional conformity verification of 3D design models, improving the comprehensiveness, accuracy, and reliability of conformity analysis, and meeting the high-precision conformity verification requirements of complex industrial products.

Abstract

The application discloses a three-dimensional design model compliance analysis method and system based on a large language model, comprising the following steps: obtaining three-dimensional design model related data and design specification constraint conditions, and building a data interaction channel through a collaborative review platform; calling a semantic geometry collaborative verification algorithm to process data and extract characteristic parameters; generating a rule adaptation weight matrix through a spatial rule learning adaptation model; constructing a mapping relationship between a characteristic vector and a design specification through a CAD point cloud characteristic coding mapping model; performing multidimensional compliance verification based on the foregoing results; and outputting comprehensive analysis data sets. Through multi-unit collaborative linkage, the system integrates algorithms and platform functions, realizes deep collaborative processing of three-dimensional design model geometry and semantic data, improves the accuracy of rule adaptation and characteristic mapping, comprehensively covers the compliance verification dimensions, and meets the high-precision analysis requirements in complex scenarios.
