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.
