The ability for users in other departments across an organization (non engineering) have access to our drawings from anywhere via web or mobile device was amazing! There is not much I did like about this system except that we didn't need it anymore because they now provide cloud software which gives us more control over data security than having everything stored locally at one location.
We used blue cherry soley internally but will be looking into moving towards using their Cloud Software as well due to increased safety/security concerns with storing any information remotely vs local server within our facility. Our main use case were CAD drawing files being able to easily share them between multiple team members who are scattered globally both inside & outside my org., without requiring everyone involved meet up physically together when sharing designs etc.
