Challenges and Issues in Migrating to an MBD Environment
The transition from a 2D drawing-based environment to a Model-Based Definition (MBD) approach constitutes a fundamental transformation in how industrial companies create, manage, and communicate their technical data. This strategic evolution comes with numerous challenges that must be identified and anticipated to ensure a successful migration.
Technical Complexity of the 2D-3D Transformation
Migration to an MBD environment is not simply about digitizing drawings. It involves a complete overhaul of how technical information is structured, enriched, and shared. Technical difficulties include:
- Precise conversion of 2D dimensions and tolerances into 3D annotations (PMI)
- Preservation of references and design intent
- Management of existing documentary heritage, sometimes considerable
- Correct interpretation of specific symbols and annotations
These technical challenges are amplified in multi-CAD contexts where the diversity of formats and modeling approaches adds an additional layer of complexity.
Organizational and Human Impact
Beyond purely technical aspects, MBD migration profoundly transforms processes and work habits. This organizational dimension manifests at several levels:
| Dimension | Impacts | Associated Challenges |
|---|---|---|
| Processes | Revision of validation and approval workflows | Redefinition of responsibilities and milestones |
| Skills | New expertise required | Training and supporting teams |
| Collaboration | Modification of interfaces between departments | Adaptation of exchange processes |
| Partners | New exchange formats with the ecosystem | Harmonization of practices with suppliers |
This transformation requires a rigorous change management strategy to support teams and minimize resistance inherent to any major change.
Strategic Issues of Digital Continuity
MBD migration is part of a broader vision of digital continuity, the backbone of Industry 4.0. The associated strategic issues are multiple:
- Preservation of intellectual capital and know-how embedded in product definitions
- Acceleration of development cycles by eliminating digital breaks
- Quality improvement through reduction of interpretation errors
- Strengthening collaboration between different links in the value chain
- Increased innovation capacity through facilitated reuse of existing designs
Methodological Approaches for Successful MBD Migration
Given the inherent complexity of any MBD migration project, adopting a structured methodology is a key success factor. Experience shows that a progressive approach, combining global strategy and targeted tactics, offers the best guarantees of success.
Preparation and Preliminary Assessment
The preparatory phase of an MBD migration project is decisive. It allows establishing a clear vision of the existing situation, objectives, and constraints specific to the organization. Key actions in this stage include:
- Audit of existing 2D documentation (volume, complexity, criticality)
- Assessment of the organization's maturity regarding MBD practices
- Identification of priority use cases and impacted processes
- Definition of measurable objectives and a realistic migration scope
- Development of a migration strategy adapted to the specific context
This assessment phase allows proper sizing of the required effort and identification of potential risks before engaging in the actual migration.
Conversion Strategies and Scenarios
The diversity of industrial contexts and documentary heritage requires fine-tuning of migration strategies. Several approaches can be considered:
| Strategy | Description | Application Context |
|---|---|---|
| Complete Migration | Systematic conversion of the entire 2D heritage to MBD | Organizations of limited size or with high technical added value |
| Selective Migration | Targeted conversion of critical or high-value models | Large groups with voluminous documentary heritage |
| Progressive Migration | Approach by successive waves, prioritizing certain product families | Organizations wishing to spread the effort and minimize risks |
| Hybrid Migration | Temporary maintenance of a dual system (2D and MBD) with targeted migration | Environments constrained by strict regulatory requirements |
The choice of a strategy must be based on an in-depth analysis of business needs, technical constraints, and available resources.
Validation and Quality Control
The reliability of data from MBD migration is a critical issue. A rigorous process of validation and quality control must be implemented to ensure the integrity and compliance of converted models:
- Systematic verification of geometry and 3D annotations
- Control of the completeness of transferred information
- Validation of compliance with applicable MBD standards
- Testing of usage in downstream processes (manufacturing, control, etc.)
- Implementation of measurable quality indicators
This validation process must be formalized and documented to ensure the traceability of operations and facilitate subsequent audits.

MBD Implementation Process and Remastering
The effective implementation of an MBD strategy goes well beyond simply setting up technical tools. It requires a holistic approach integrating technical, organizational, and methodological aspects.
Optimized Workflow for MBD Migration
Establishing a structured workflow is a key success factor for any MBD migration project. This process must be both rigorous and adaptable to the specifics of each organization:
- Preparation and analysis: Evaluation of source drawings, identification of special cases, resource planning
- Automated conversion: Batch processing of 2D drawings with DrawtoPMI, generation of annotated 3D models
- Technical validation: Systematic quality control, comparison with 2D sources, compliance verification
- Targeted remastering: Manual intervention on complex cases or elements not automatically converted
- Final validation: Technical approval, compliance check with standards, business validation
- PDM/PLM integration: Registration in management systems, creation of associated metadata, establishment of links
This workflow must be adapted to the specifics of the organization, taking into account operational constraints and team maturity levels.
Remastering and Completion Tools
Despite significant advances in automatic conversion technologies, some complex situations still require manual intervention. Specialized tools facilitate this remastering:
- Annotation assistants guiding the creation of complex PMI
- 2D/3D visual comparison systems for validation
- Tools for detecting inconsistencies and anomalies
- Libraries of pre-configured standard elements
- Automation mechanisms for repetitive tasks
These remastering tools optimize human intervention by focusing it on high value-added aspects requiring expertise and judgment.
Integration into the PLM/PDM Ecosystem
Migration to an MBD environment cannot be considered in isolation from product lifecycle management systems. Seamless integration with the existing PLM/PDM ecosystem is essential:
This integration must cover several dimensions:
- Management of metadata and attributes specific to MBD models
- Implementation of approval workflows adapted to new formats
- Revision management and configuration of annotated 3D models
- Traceability of conversion and validation operations
- Visualization mechanisms adapted to annotated 3D models
This integration ensures the global coherence of the technical information system and maximizes the benefits of MBD migration.
