Our client, a leading automotive tier-one supplier, approached us with the objective of migrating their CAD systems from CATIA V5 to CATIA 3DEXPERIENCE. This migration aimed to enhance their product development capabilities, streamline collaboration, and leverage the advanced functionalities of the 3DEXPERIENCE platform. However, the migration presented several technical challenges due to differences in architecture, data handling, and compatibility between the two platforms.
During the migration, references between assemblies (CATProduct) and their child parts were broken, resulting in lost connections and requiring manual re-linking.
CATIA V5 drawings stored references differently than CATIA 3DEXPERIENCE. In V5, drawings were saved with reference links, while in 3DEXPERIENCE, drawings are integrated into CATParts with relational connections. This led to broken links during the migration process.
Parametric features such as formulas and design tables in V5 did not seamlessly translate into 3DEXPERIENCE, resulting in the loss of important design intelligence.
Metadata such as part numbers and associated drawings required accurate mapping, but inconsistencies between the two systems complicated this process.
Conflicts arose while mapping different revisions and versions of assemblies, parts, and drawings between the V5 and 3DEXPERIENCE environments.
Data loss occurred when transferring file formats like STEP, IGES, and CGR from V5 to 3DEXPERIENCE.
Assembly constraints, such as mate and offset, did not always migrate correctly, leading to misaligned assemblies in the new system.
Rules, macros, and knowledge templates developed in V5 were often incompatible with the 3DEXPERIENCE platform, requiring redevelopment
Custom scripts and tools were developed to identify and repair brokenassembly and drawing links during the migration process, reducing manual effort.
A specialized mapping algorithm was implemented to convert V5 drawing references into the relational format used in 3DEXPERIENCE, ensuring seamless connectivity.
Advanced translators were utilized to migrate parametric features such as formulas and design tables while retaining design intent. For complex cases, manual adjustments were made.
A specialized mapping algorithm was implemented to convert V5 drawing references into the relational format used in 3DEXPERIENCE, ensuring seamless connectivity.
A version control mechanism was established to handle conflicts during the migration of revisions and versions, ensuring all changes were accurately reflected.
High-fidelity file format converters were employed to minimize data loss when transferring STEP, IGES, and CGR files.
Assembly constraints were validated and repaired using custom validation scripts to ensure alignment in the migrated assemblies.
Knowledge templates, rules, and macros were reviewed, updated, or redeveloped to ensure compatibility with the 3DEXPERIENCE platform.
The 3DEXPERIENCE platform provided a unified environment for design, analysis, and collaboration, improving cross-functional teamwork.
Automated tools and processes minimized data loss and maintained the integrity of assemblies, drawings, and metadata.
The migration enabled the client to utilize advanced functionalities of the 3DEXPERIENCE platform, such as real-time collaboration, lifecycle management, and data analytics.
Automated link repair and parametric feature translation reduced the time and cost associated with manual corrections.
The migration positioned the client to take advantage of future enhancements and capabilities offered by the 3DEXPERIENCE platform.
