Business Administration1#Maintaining data consistency is a mustWhat 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 PartDo different design/product/organizational disciplines have differing needs?

PreparationSystem Administration, Configuration and Process considerationsSTARTENDDefining a New Product ConceptUsing enterprise top down design2PreparationLeveraging New Windchill 10.0 capabilities to the fullest1Detailed Design Execution3Finalizing Product Structure4Available for downstream activities/systems5#Identify File-based or Non-file-based attributes required for CADDesignated Dimensions / Parameters coming from CAD authoring tools (file-based)Attributes strictly managed in WindchillIdentify and define any constraintsWhat CAD attributes should be propagated to its related Part?Building Part structure from CAD propagates attributes to the PartAll, Some, maybe None PreparationAttribute Management1

#Desiring certain behavior based on a given authoring tool.Wanting more granular control of attributes that might be applicable for specific model types or disciplinesPrevious Windchill Releases have all attribute go on a single type. For example: If Im modeling a bearing, there may be attributes that are not applicableManaging differing OIRs (conventions and life cycles) for different disciplines.

Expanded CAD Document Soft-type support with 10.0Possible use cases may be one of the following1

Support for multiple CAD document soft typesSelect while Creating New CAD Document in WorkspaceNew Create New CAD Document while creating New PartDrive type created based on CAD model attribute (parameter) valueUse designated parameter UPLOAD_SOFT_TYPEDrives creation on upload of content to serverMap CAD Document softtype to Part soft typesAs part of CAD documentsoft type definition

Enterprise Top Down Design

2010 PTCChallenge: Design complex multi-disciplined productsPractice: Develop hi-level product architecture that drives a defined set of MCAD design deliverables used in concurrent and iterative development of complex productsCapabilities:Simultaneous creation of enterprise part & associated CAD structuresInteractive preview for conceptual development of design structures and validationConcurrent editing of associated structures with pro-active reconciliation of differencesSynchronize and drive controlled changes throughout concurrent design developmentBenefits:Engineer products from top-downShorten time to design by enabling concurrent design processEliminate manual rework with automated communication of changesCreate initial enterprise product architectureCreate corresponding CAD deliverablesDrive CAD deliverablesManage changes and relationships
