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.
Validate CAD model quality
CADIQ validation solutions combine our leading expertise in interoperability improvement consulting with innovative validation technology. CAD Interop and ITI help customers put processes in place that help identify and manage the correction of problems stemming from design quality and product data interoperability issues. Resolution of these challenges is critical in order to improve downstream product data re-use. We have been involved in developing software solutions and consulting methodologies based on real customer challenges for over 15 years and we are well positioned to understand the requirements of, and deliver solutions for each customer's unique needs.
CAD validation includes:
- Identify bad geometry that impedes re-use of models in analysis and manufacturing processes
- Identify unrealistic modeling features requiring changes during CAE/CAM model re-use and divergence between the master product model and downstream CAx models
- Highlight unacceptable changes introduced during translation, migration, archiving or manual re-mastering
- Highlight undocumented changes arising between design revisions or for engineering change orders
- Find changes caused by complex parametric relationships unknown to CAD users
- Find changes to assembly product structure models that were not anticipated
Identify quality and shape changes between revisions of a design model. Verify that any previous quality defects have been resolved. 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.
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.
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.
Identify quality defects in the design model that impede 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. When 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.
Identify derivative difference introduced while upgrading a model to a different version of a same CAD system.
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.
