3D PMI Display Switching for Repeated Feature Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When product manufacturing information (PMI) is displayed for only a representative feature of multiple identical features in a three-dimensional model, it becomes difficult to understand the PMI for the other features, especially during enlargement or when users unfamiliar with the design inspect the model.
Innovation Solution
An information processing system with a processor that displays PMI for only a representative feature of multiple identical features, but switches to individual display of PMI for each feature when certain conditions are met, such as enlargement, user attribute, development step, or operation history, ensuring that PMI is always accessible and understandable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If product manufacturing information is displayed for only a representative feature to reduce display complexity, then device complexity is reduced, but information completeness deteriorates
Solution Approach 1:
The display mode dynamically switches between collective display (showing PMI for representative features only) and individual display (showing PMI for each feature) based on user interactions such as selection operations or enlargement actions. This dynamic adaptation resolves the contradiction by adjusting information display density according to real-time user needs.
Solution Approach 2:
The system applies different display strategies to different features: representative features are displayed with collective PMI when in overview mode, while specific selected features receive individual PMI display when users need detailed information. This local differentiation allows the system to optimize both overall display complexity and specific information accessibility.
2Ease of operation
If product manufacturing information is displayed for only a representative feature, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The system prepares both collective display data (for ease of overview) and individual feature PMI data (for precise measurement information) in advance. When users perform selection or enlargement operations, the system can immediately switch to displaying precise individual feature information without requiring additional data processing, thus maintaining both ease of operation and measurement precision.
3Productivity
If product manufacturing information is displayed for only a representative feature, then productivity is improved, but reliability deteriorates
Solution Approach 1:
The system monitors user interactions (selection operations, enlargement actions) as feedback signals and automatically adjusts the display mode accordingly. When users indicate need for detailed information through these interactions, the system switches from collective to individual display, ensuring reliable PMI understanding while maintaining high inspection efficiency through automated adaptation.

AI summary
An information processing system includes a processor configured to: display product manufacturing information for only a representative one of plural features of a same shape included in a three-dimensional model represented by three-dimensional drawing data; and switch, if a preset condition is satisfied, between display of the product manufacturing information for only the representative one of the plural features and individual display of the product manufacturing information for each of the features.
