The "Loads" grid is analogous to the "Loads definition" window. Loads applied to the structure using the "Loads definition" window are listed in the "Loads" grid.
This table can also be filled in manually. To do this, click the drop-down button 
in the "Type" column and select the desired load type. Depending on your selection, one or more fields will become accessible for editing. All text fields can be filled in by typing. The "Type" and "Direction" columns both feature drop-down lists with all available options. You can enter a node or member number in the "Member/Node" column simply by typing the number without any prefix.
The first column of the last row (marked with an asterisk *) is always available for adding a new load.
Adding load cases:
Loads are organized into load cases, which are displayed as tabs at the bottom of the "Loads" grid.
Default case: You will always see at least one default load case (LC1).
Adding new cases: Once you add loads to LC1, a second load case tab will automatically appear. To create additional load cases, simply click the next available tab and apply your loads.
Please note that only load cases containing data (filled-in load cases) will appear in the drop-down list within the Structure view.
