Product Data Quality and Validation Scenarios

Legacy Design Migration Validation

Identify quality and shape changes introduced while migrating a CAD model from a legacy system into your current design system. The migration method can be BREP translation, feature translation or manual remastering. When using neutral file exchange (IGES, STEP, Parasolid), identify if any changes are introduced during export or import. Compare migration methods to identify the best options.

Design Translation Validation

Identify quality and shape changes introduced while translating a CAD model from a supplier or partner’s design system into your design system. The translation method can be BREP translation, feature translation or manual remastering. When using neutral file exchange (IGES, STEP, Parasolid), identify if any changes are introduced during export or import. After manually remastering a model, compare design revisions to identify shape changes to guide manual updating of the remastered model (to avoid divergence). Compare translation methods to identify the best options.

Design Revision Validation

Identify quality and shape changes between revisions of a design model. Verify that any previous quality defects have been resolved. Determine if any unintentional changes have been introduced.

Design for Simulation Validation

Identify quality defects in the design model that impede reuse for simulation modeling. Identify the design features that cause each defect to help the designer effectively remove it. Identify shape changes between the design and simulation models to verify that they are acceptable within simulation objectives. Compare design revisions to identify shape changes to guide manual updating of the simulation model (rather than rebuilding it for each design revision).

Design for Manufacturing (Tooling) Validation

Identify quality defects in the design model that impede reuse for manufacturing, e.g. tooling design. Identify the design features that cause each defect to help the designer effectively remove it. Identify shape changes between the design and manufacturing models to verify that they are acceptable within manufacturing requirements. Compare design revisions to identify shape changes to guide manual updating of the manufacturing model (rather than rebuilding it for each design revision).

Engineering Change Validation

Identify quality and shape changes introduced during modification of a design model for an engineering change request. Verify that the modified model has no quality defects which will impede anticipated downstream use of the model. Verify that all required changes were made as specified and that no unintentional changes were introduced. Use this to verify that the change documentation is complete and accurate. Complement the documentation with static and/or dynamic 3D graphics which highlight and quantify the changes.

Design Data Delivery Certification

Verify that the design model has no quality defects which will impede anticipated downstream use of the model. Verify that any derived forms of the design model (IGES, STEP, CAD translations…) are equivalent in quality and shape to the master model. If using STEP, add validation properties to the STEP model which can be used by the recipient to validate that a translated (imported STEP) CAD model is equivalent to the master model.

Long-Term Archival Validation

Document any quality defects in the design model to set appropriate expectations for the reusability of the archive data. Verify that any derived forms of the design model, e.g. STEP, are equivalent in quality and shape to the master model. If using STEP, add validation properties to the STEP model which can be used by a future recipient to validate that a future translated (imported STEP) CAD model is equivalent to the master model. These validation properties could also be used to verify the equivalence of any archive data format conversions which are required to maintain the archive over time.
