## Enterprise Design and Analysis Information Integration with ISO 10303-209

- Enables sharing of PDM
- 	controlled composite and
- 	metallic design, analysis,
- 	material properties/specs information
- Enables automated, electronic feedback of product shape, performance, and property analyses to CAD with respect to PDM product structure and versioning
- Platform to extend engineering analysis STEP coverage into other analysis disciplines such as Fluid Dynamics
- Provides a long term, potentially growing, repository crucial to many industries and vendors
- Neutral format for PDM/CAD/CAE

## Standard PDM Design Information Management

- Indentured list of assemblies and components
- Configuration and revision management
- Associated data management
- Design shape model(s)
- Other related design information

## AP209 Enables Analysis Feedback to Design

- The original Part1 and it’s nominal design shape (NDS1) for a point of reference (node to hook into PDM)
- Part1_Version2, the final Analysis_Version2 (FEM3) and the idealized analysis shape that reflects the performance requirement changes (IAS3)
- The analysis report containing the rationale documenting the design changes (modes/frequencies, stiffener buckling, model idealization and tuning process)

## Integration of Design and Analysis Information in a PDM is a Powerful Systems Integration Approach

- ISO 10303-209 provides a standardized meta-model for the implementation of PDM Design - Analysis data management
- PDM Customization straight-forward
- Automation of a PDM - managed Design - Analysis cycle furthers the goal of truly integrated systems
- AP209 provides a standardized capability to share information between Design and Analysis disciplines
