The function "Groups" is only to give access in the workspace. You can add a user to a group and then give the group rights to selected folders in the workspace.
Usually you create groups to different roles in the project - One to the project owner, one to the architects, some to the different advisers and maybe some to the contractors who needs access in the workspace.
As a project administrator you can create, edit and delete groups. The first time you create a group, you can also add users. But you can also add users later, by the same way, or when you add a user to the project.
Create a group - How to:
- Open the Project
- Go to "Project administration"
- Click on "Groups"
- Click on the button "Create group"
- Enter the name of the group and select group members
- Click "OK"
NB: If you want to edit or delete a group, you need to mark the group and then click on the button "Edit group" or "Delete group".
