In Windchill 10.0 PTC is introducing new enterprise top down design capabilities. This great new capability allows non-CAD users to edit or create product structures (tied to CAD), perhaps to capture a new product design concept or change. Once satisfied with their design choices he/she has the power to propagate these changes (or ideas) down to the CAD assembly, creating new CAD structures which can seamlessly be passed along to the design engineer, where the update CAD design is retrieved and the more detailed design work can be completed.
Some of the key capabilities in Windchill 10.0 that make this possible include:
Here’s a short video which captures this new 10.0 capability in action:

Windchill 10.0 enterprise top down design is planned to initially support Creo Elements/Pro 5, CATIA V5 and NX CAD authoring applications.
