Skeleton Model Not Built Builds Component Part Builds Assembly Part Builds Component Part Enterprise Structure CAD Structure Requirements Data Sheet CAD Model Data Sheet Viewable Requirements Test Plan Software Code Analysis Test Plan Software Code Analysis CAD Model Viewable Test Plan Software Code Analysis CAD Model Data Sheet Viewable Requirements

4 4 Storyboard Overview START END Defining a New Product Concept Using enterprise top down design Defining a New Product Concept Using enterprise top down design 2 2 Preparation Leveraging New Windchill 10.0 capabilities to the fullest Preparation Leveraging New Windchill 10.0 capabilities to the fullest 1 1 Detailed Design Execution 3 3 Finalizing Product Structure 4 4 Available for downstream activities/systems 5 5 Enterprise Top Down Design 2 2 Detailed Design 3 3 Reconcile CAD-to-Part Relationships 4 4 Downstream deliver/usage 5 5 Business Administration 1 1

5 5 Maintaining data consistency is a must What CAD tools does the system need to manage & do they have differing needs? What information should be extracted from the CAD models? – relevant to Search? – does it contain information relevant to the Part Do different design/product/organizational disciplines have differing needs? Preparation System Administration, Configuration and Process considerations START END Defining a New Product Concept Using enterprise top down design Defining a New Product Concept Using enterprise top down design 2 2 Preparation Leveraging New Windchill 10.0 capabilities to the fullest Preparation Leveraging New Windchill 10.0 capabilities to the fullest 1 1 Detailed Design Execution 3 3 Finalizing Product Structure 4 4 Available for downstream activities/systems 5 5

6 6 Identify File-based or Non-file-based attributes required for CAD – Designated Dimensions / Parameters coming from CAD authoring tools (file-based) – Attributes strictly managed in Windchill – Identify and define any constraints What CAD attributes should be propagated to its related Part? – Building Part structure from CAD propagates attributes to the Part – All, Some, maybe None Preparation Attribute Management 1 1

7 7 Desiring certain behavior based on a given authoring tool. Wanting more granular control of attributes that might be applicable for specific model types or disciplines – Previous Windchill Releases have all attribute go on a single type. – For example: If Im modeling a bearing, there may be attributes that are not applicable Managing differing OIRs (conventions and life cycles) for different disciplines. Expanded CAD Document Soft-type support with 10.0 Possible use cases may be one of the following 1 1

8 8 Support for multiple CAD document soft types Select while Creating New CAD Document in Workspace New Create New CAD Document while creating New Part Drive type created based on CAD model attribute (parameter) value – Use designated parameter UPLOAD_SOFT_TYPE – Drives creation on upload of content to server Map CAD Document soft type to Part soft types – As part of CAD document soft type definition Forward looking information subject to change without notice © 2010 PTC Select CAD Document Type 1 1

9 9 Support for multiple CAD document soft types Define types based on authoring tools – Ex. Different soft types for Creo and AutoCAD – Site wide configuration using EPMDefaultSoftTypes.xml Forward looking information subject to change without notice © 2010 PTC 1 1
