The "Project" frame is used to input basic project data.
The "Project data" button (1) opens a dialog window in which you can fill in individual items.
If the project data you enter does not suit you, you can change it as you need (add / edit / delete). The data is defined in the so-called "Project data template". After pressing the "Project data template" button (3), the "Edit project data template" dialog window opens.
