概要About the project01

We developed a system for automated comparison of CAD models that cuts change analysis time from 15 to 2 minutes. The algorithm highlights geometric changes and generates a PDF report for engineers.

課題Key challenge02

Complex geometry with thousands of polygons, varying CAD file formats, and the need to work with model deltas without fully rebuilding the models.

Part inspection service
要点The solution

Built for an automotive plant, the packaged system runs on a decision tree model that compares key features (holes, stiffening ribs, and more) one by one. The comparison follows the engineering checklist that engineers used to check by hand before the system was deployed. The standalone service now saves the plant up to 10 hours of specialist time per week.
