DrawtoPMI automatically converts a 3D CAD model and its associative 2D drawing to a single 3D part file containing product manufacturing information (PMI).

DrawtoPMI is essential for any company implementing a 3D model-based design (MBD) environment. It enables fast and efficient legacy data migration for MBD use, while eliminating expensive, error-prone manual migration processes.


  • Support for FT&A features, including datums, dimensions, feature control frames and annotations
  • Support for semantic and non-semantic FT&A features
  • Preservation of the original associativity with the 3D model geometry
  • Conversion of 2D drawing view names and orientations to 3D PMI “Capture” features
  • Support for associative views, including projection, section, detail and isometric

Legacy data migration for MBD

If your company is implementing MBD, then 3D CAD models for future projects will be created with the PMI data included. But what about legacy CAD parts that need to be used in the new MBD environment?

Until now, the only option available to migrate legacy data for MBD use is a labor-intensive and error-prone process in which a designer manually interprets and extracts the PMI data from the 2D drawing and adds it to the 3D part.

By automatically combining the legacy 3D part and 2D drawing files, DrawtoPMI saves months of manual work and provides a compelling return on investment.

Non-associative dimensions

DrawtoPMI also transfers non-associative dimensions to support the need for everything in the 2D environment moving to the 3D world.

Although some dimensions are created as non-associative in source drawings, DrawtoPMI creates them as 3D PMI entities.

The model shown here had dimensions that were non-associative in the 2D drawing. These dimensions are still preserved as 3D FT&A, but are noted with a darkened color to alert the user.  The user can choose to keep the dimensions as they are, or re-link the dimensions to appropriate geometry for automatic updates.

Rapid return on investment

DrawtoPMI can complete processes automatically in less than a minute, where the manual alternative could take more than a day, depending on the level of complexity in the PMI.
