Establishment of Inspection Information Model Based on Secondary Development with CATIA

Aiming at the requirement of 3D model quality inspection, this paper establishes the inspection information model based on CATIA V5R21 development platform under C# and C++ development environment, combines with the actual production inspection technical documents, compiles the CATIA-based basic inspection information extraction and extraction inspection technology related content, and jointly establishes the inspection information model system program. The system integrates the data of inspection technical documents with the relevant digital inspection system of aviation manufacturing enterprises, and forms a closed-loop process of product design-process-manufacture-inspection-design, which provides effective data support for the later development and improvement of products.
