When you look at most organizations who design using CAD tools, almost all use the .PDF format to share files with others. The .PDF file format is easy to share, works consistently and most everyone has access to software to open them.
The problem that most companies face with this process is that someone has to manage these files. Doing this requires someone to know where it needs to be placed, whether to overwrite and old version of the .PDF or, move it. Don’t forget, they must remember the naming scheme so it can easily be identified as the latest and all while timing this with a change. It is a very resource intensive function and requires precision. If done incorrectly, there is a potential for the wrong data to go to the wrong person. An example would be if someone from the purchasing department was looking for the latest version to send to a vendor for manufacturing and they grab an old revision because someone forgot to generate the .PDF or made a mistake.
