Sharing AssembliesWithout 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.
