Aconex is not just a file sharing software. It’s a platform for managing project information.
I don’t know if there is any Aconex training Center in Qatar. But watch this Video which is enough to start with. In our Project we use Aconex and the employees we were given a training of about 2 hours at the beginning by Aconex Team, And now everyone started to work with it.
