Comprehensive CAD Data Migration & Engineering Data Transformation

“Converting legacy engineering data into intelligent, manufacturing-ready CAD assets while preserving engineering intent and preparing the data for future reuse and PLM integration.”

Engineering organizations often accumulate product data across multiple generations of CAD systems, acquired companies, legacy paper drawings, scanned documents, 2D CAD files, non-standard 3D models, and inconsistent design practices.

As CAD platforms evolve, organizations face challenges such as:

  • Legacy paper drawings requiring digitization
  • 2D CAD drawings needing intelligent 3D conversion
  • Migration between different CAD platforms
  • Non-standard modeling practices that limit reusability
  • Product data spread across multiple engineering teams and acquisitions
  • Missing design intent in imported or dumb solid models
  • Lack of standardization for future engineering modifications
  • Preparation of engineering data for PDM/PLM systems

Our CAD Migration Services transform historical engineering information into intelligent, standardized, and future-ready CAD assets that support design, manufacturing, simulation, documentation, and product lifecycle management.

CAD migration intro

Engineering Data Standardization & Migration Readiness

Before migration begins, engineering data often requires organization, standardization, and preparation to ensure consistency across the product portfolio.

Scope Includes

  • CAD data assessment and classification
  • Identification of duplicate, obsolete, and redundant data
  • Standardization of modeling practices and naming conventions
  • Part numbering and classification strategy support
  • Assembly structure optimization
  • Metadata and custom property standardization
  • CAD environment and template standardization
  • Migration readiness preparation for PDM/PLM systems
  • Creation of migration workflows and validation procedures

This foundation ensures that migrated engineering data remains maintainable, searchable, and reusable long after the migration project is completed.
