Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
CAD models migrated from older versions or systems to newer ones often become 'dumb' solids, lacking creation information, which reduces user control over model components.

Engineering Contradiction Analysis
1Adaptability or versatility
If CAD models are migrated from older CAD system versions to newer versions, then compatibility and accessibility are improved, but the models become 'dumb' solids lacking creation information, reducing user control
Solution Approach 1:
The system performs preliminary actions by generating bounding planes and storing them in the migrated model before the user needs them. The bounding planes are created during the migration process itself, so when the user later needs to perform operations like clash detection or boolean operations, the necessary geometric information is already available without requiring access to the original creation system.
Solution Approach 2:
The bounding planes serve as an intermediary structure that bridges the gap between the migrated dumb solid and the user's need for control. Instead of requiring access to the original parametric definition, the system introduces bounding planes as intermediate geometric elements that provide the necessary control surfaces for downstream operations while being compatible with the target CAD system.
2Adaptability or versatility
If CAD models are migrated between systems, then interoperability is improved, but user control over model components is reduced
Solution Approach 1:
The system segments the model control into two parts: the migrated solid geometry itself and the generated bounding planes. This segmentation allows the solid to be migrated as a dumb solid for compatibility, while the bounding planes provide separate, accessible control surfaces that users can manipulate independently for operations like clash detection, material assignment, and boolean operations.
Solution Approach 2:
Bounding planes act as intermediary control elements that restore user control without requiring access to the original parametric definition. These planes provide a level of control between the fully parametric original model and the completely dumb migrated solid, enabling users to perform operations on specific surfaces while maintaining interoperability with the target CAD system.
3Ease of operation
If bounding planes are generated for migrated models, then user control and model configuration capability are improved, but processing complexity increases
Solution Approach 1:
Instead of attempting to recover or recreate the original complex parametric definition, the system creates simplified copies in the form of bounding planes. These planes are exact geometric copies of the outer surfaces needed for control operations, but without the complexity of the original parametric history. This copying approach provides sufficient control for most operations while keeping processing complexity manageable.
Solution Approach 2:
The system extracts only the essential geometric information needed for user control operations - specifically the bounding surfaces - and separates this from the full parametric model structure. By taking out only the necessary bounding plane information rather than attempting to preserve or recreate the entire parametric definition, the system reduces processing complexity while maintaining adequate model configuration capability.
