Sharing Assemblies Without giving it all away!  Have you ever wanted someone else’s product to add into your own assembly model?  Have you ever ended up “NOT” finding their product on-line and available for download?  Have you ever thought of sharing your product but chose not too because of the fear of sharing too much?  This is a real, daily occurrence and it’s serious.  The risks are missed opportunities and competitive copying. Why Do This Presentation?: 2

Sharing Assemblies Without giving it all away!  Positives:  Market Awareness  Builds Relationships  Speed/Confirm Selection  Test; Fit, Form, Function  Minimize Repeated Effort  Complete the Design. Why Share At All?  Negatives:  Loss of Proprietary Info  Loss of Competitive Adv  Aid Knock-off Efforts  Source Elsewhere  Managing Data. 3
