I would like to know what is the workflow in archicad, what I usually do in revit is to create folders by specialty and work in each of these the file separated by specialty linking the files so that the file is not heavy, I would like to know if this also it is done the same in archicad with a local server and if it would also be the same with bim cloud?
The workflow you mentions is completely working in case of ARCHICAD and BIMcloud Basic too.
In BIMcloud Basic you can create only one level of folders (= no subfolders inside a folder, this is a licensed feature). From ARCHICAD side, you can hotlink several files to one host project, where the hotlink modules can be either local files (.pln, .mod or IFC related files), or coming directly from another Teamwork project.
If you wish to learn more about Teamwork and BIMcloud, I recommend you to check our videos in the topic, especially this one:
