5. PDElib and GDX Support for AP242
PDElib is a software development toolkit used by ITI and CAD vendors to develop standards based CAD data exchange applications
GDX is the ITI neutral interoperability file format integrated with PDElib
AP242 Support
Assembly structure, part geometry and attributes for AP242
AP242 PMI semantic representation and graphic presentation data
Imports and maintains the relationship between corresponding PMI elements and geometry from AP242
Supports PMI based on new tessellated entities as well as polyline
A mapping between AP242 and the GDX file format is established to enable verification, validation and import within the ITI CADIQ and CADfix interoperability solutions

6. Identify design defects
CADIQ and STEP AP242
CADIQ is a multi-CAD application that identifies problems and differences in CAD models that can impact downstream applications such as analysis, manufacturing, data exchange and long term archival
CADIQ uses PDElib and GDX for AP242 support
AP242, AP203, AP214

7. CADIQ and STEP AP242 Use Cases
Direct Validation
CADIQ uses the CAD system’s programming interface to determine if an exported or imported STEP file is equivalent
Saved View Validation
CADIQ validates that the CAD and STEP models’ geometry and PMI entities are equivalent within each saved view
Graphical and Semantic PMI Validation
CADIQ validates that the CAD and STEP PMI definitions are equivalent at two levels: graphical presentation for visual consumption and semantic representation for automated consumption
PMI Quality Checking
CADIQ identifies defects in the semantic representation and graphical presentation of 3D annotations in both CAD and STEP models
STEP Validation Property Augmentation
If an exported STEP model is missing a validation property, CADIQ will evaluate it within the native CAD system and append it to the STEP file
STEP Validation Property Quality Checking
CADIQ identifies STEP validation properties which are incomplete or inaccurate

8. Direct Validation of STEP AP242 Export
CADIQ uses the CAD system’s programming interface to determine if an exported or imported STEP file is equivalent
Revolved faces are lost during STEP export
STEP Model
Native Model

9. Direct Validation of STEP AP242 Export
Complex blend (procedural surface in native model) is approximated in STEP export and produces a deviation of inch (0.1 mm)
Native Design Model
STEP Delivery Model

10. Graphical and Semantic PMI Validation
CADIQ validates that the CAD and STEP PMI definitions are equivalent at two levels: graphical presentation for visual consumption and semantic representation for automated consumption
PMI presentation graphics changed
Native Model
Migrated Model
PMI Semantic definition changed

11. Graphical and Semantic PMI Validation
Indentify PMI data that has been removed, added or modified during a translation process
Unmatched Annotations
User error or incorrect export options mean that no PMI is exported or translated
Annotation Differences
Different interpretation of PMI data or errors occur during export or translation
CADIQ identifies inconsistencies in the display of Graphical PMI data
CADIQ Semantic PMI validation will overlook negligible presentation differences

12. STEP PMI Quality Checking
CADIQ identifies defects in the semantic representation and graphical presentation of 3D annotations in both CAD and STEP models

13. STEP Validation Property Checking and Augmentation
Incomplete or Missing Validation Properties
Detect if an exported STEP model is missing a validation property
CADIQ will evaluate it within the native CAD system and append it to the STEP file
Inaccurate Validation Properties
CADIQ will assess the validation property data in the STEP file and determine the accuracy of that data relative to the CAD model
GDX geometry model and evaluators used to derive “2nd CAD system” validation properties for comparison

14. CADfix and STEP AP242
CADfix is a multi-CAD import, repair and advanced defeaturing solution for CAD/CAM/CAE integration
CADfix uses PDElib and GDX for AP242 support
AP203 and AP214 import for BREP geometry parts and assemblies
Extended to support the import of PMI Presentation and Semantic data from AP242
Maintains links between PMI data and STEP geometry
PMI Display and Browsing

15. DEXcenter and STEP AP242
Offers OEMs and suppliers a secure, SOA-compliant, vendor-neutral platform for automating CAD/CAM/CAE/PLM interoperability workflows
Enables the fully automatic translation and validation of AP242 files and creation of Technical Data Packages (TDP) for delivery within a collaboration environment
AP242 Support
DEXcenter supports AP242 through the CAD vendor STEP translators
Automated AP242 quality checking through the integration of CADIQ
Automated AP242 import and export validation though the integration of CADIQ
Support for MBD TDP of which AP242 is a part

16. Summary
ITI supports STEP AP242 in its CAD model translation, verification, validation and process automation solutions
PDElib and GDX – translation library support
CADIQ – AP242 verification and validation
CADfix – AP242 model import and viewing
DEXcenter – collaboration process automation
Support for STEP AP242 within ITI solutions will continue to develop in line with market requirements and customer demands
