I used to work with Archicad since 2007 till 2019, when I had left the profession of architect.
However I have saved all my projects on my HD, but I do not have the software any more.
Could someone please help me to exctract the list of the participants on certain projects in the term of working hours and other details.
Thanks in advance for your help
Unfortunately this is not possible from either PLN / PLA files or from BIMProject / Archive files. Current participants of a project is stored within the BIMcloud Server's databases, and none of our applications registers how many hours a user worked with them. If you already uninstalled all of these applications, I'm afraid there's no way to gain these informations.
