An European aerospace manufacturer discovered a shocking reality during their CAD migration audit: 73% of their 15,000 parametric models lose their design intelligence during the traditional conversion process. This revelation unveils a hidden cost of 2.8 million euros annually in engineering hours lost to manually rebuild erased geometric relationships.
This issue illustrates the critical challenge of parametric CAD migration in the manufacturing industry. Beyond simple geometry transfer, preserving design intelligence represents a major technological challenge that directly impacts the value of the company's digital assets.
Issue of information loss during migrations
Traditional CAD migrations generally limit themselves to transferring visible geometry, neglecting the parametric infrastructure which constitutes the real added value of modern 3D models. This superficial approach transforms years of smart design investment into simple static solid bodies.
Loss of parametric information directly generates operational consequences. Engineering teams lose the ability to quickly modify models, forcing product changes through full rebuilds. This rigidity hampers development agility and multiplies technical data maintenance costs.
Critical impact
73% of models lose their design intelligence
Economic value of parametric history
Parametric history represents intellectual capital accumulated over several decades of product development. Each geometric constraint, parametric relation and design intent constitutes intangible assets economically quantifiable.
Industry studies reveal that rebuilding a complex parametric model requires on average 40% more time compared to its initial parametric modification. This productivity gap economically justifies investment in advanced migration technologies.
Costs of parametric loss
| Impact | Average cost |
|---|---|
| Manual reconstruction | 40% additional time |
| Loss of flexibility | 60% delay modification |
| Redesign errors | 15% quality costs |
| Team training | 25% temporary productivity |
Preserving parametric history transforms a technical migration into a strategic investment. Models retain their evolution capacity, maintain team productivity and preserve the expertise accumulated in original design intents.
Parametric migration technologies
Advanced conversion technologies
Parametric migration requires specialized technologies capable of analyzing, interpreting and reconstructing design intelligence.
Difference between geometric and parametric conversion
Geometric conversion only transfers visible surfaces and volumes, producing fixed models without modification capacity. This approach simplifies technical processing but destroys the added value of source models.
Parametric conversion analyzes the construction tree, identifies geometric relationships and reconstructs the design logic in the target environment. This complex technology requires a deep understanding of each CAD system's specificities.
The complexity gap between these two approaches explains why generalist tools usually limit themselves to geometric conversion, leaving enterprises facing partial solutions for their strategic challenges.
Intelligent conversion
Analysis and reconstruction of design logic
Preservation of relationships and constraints
Geometric relationships define the interactions between different elements of a CAD model. Dimensional, angular or positional constraints ensure geometric coherence during parametric modifications.
Preserving these relationships requires precise mapping between source and target systems. Each type of constraint must be identified, analyzed and reconstructed according to the destination system specifications.
Assembly constraints present particular complexity as they involve relationships between multiple components. Their correct migration determines the dynamic behavior of the assembly in the target environment.
This multi-level preservation distinguishes advanced migration technologies from standard conversion tools. It guarantees operational continuity of existing design processes.
Preservation of design intents
Design intents represent the business logic encapsulated in CAD models. They define not only how the model is constructed but also why certain geometric decisions were made.
This conceptual intelligence includes modeling strategies, optimized construction sequences and company-specific business rules. Its preservation allows future design teams to understand and effectively extend existing models.
Migration technology must therefore go beyond simple geometric translation to reconstruct this business logic in the target environment, thus preserving accumulated intellectual value.
Proficiency solution for intelligent migration
Modular architecture
Collaboration Gateway and Proficiency Agent
Proficiency offers a modular architecture specifically designed to address the challenges of parametric migration. This technical solution relies on two main components: Collaboration Gateway and Proficiency Agent.
The Collaboration Gateway manages the interface between different CAD systems, ensuring bidirectional communication and data synchronization. This abstraction layer simplifies the complexity of multi-system interactions.
Modular architecture and technical components
The Proficiency Agent is the parametric conversion engine. It analyzes source models, identifies geometric structures, and reconstructs the construction tree in the target system. This specialized artificial intelligence handles the technical specificities of each CAD environment.
The modular architecture allows fine-tuning to the specific needs of each migration. Conversion rules can be customized according to company standards and particular sector requirements.
This modular approach guarantees the scalability of the solution. New CAD formats, specific business rules or regulatory constraints can be integrated without questioning the overall architecture.
The separation of responsibilities between different modules also optimizes processing performance, particularly critical during large volume technical data migrations.
Automated conversion and success rate
Proficiency technology achieves automated conversion rates of up to 90% for parametric functions. This performance level results from advanced analysis algorithms and an extensive knowledge base of CAD specificities.
The 10% of functions requiring manual intervention generally correspond to non-standard modeling or practices specific to the source company. This residual proportion remains predictable and manageable in project planning.
Extended automation drastically reduces migration times while minimizing human error risks. This technical efficiency directly translates into significant cost and time savings.
