Changes to the loads that are applied to the structure, may be made in the Load window.  Loads may be added to the structure or removed from it and can be applied as a number of different load cases.  These load cases may be factored together to produce combined load cases if desired.

Loads are entered in the current load units as controlled by the Units… command from the View Menu.

All of the commands under the Load menu operate on the current load case.  The name of the current load case is displayed in the bottom left hand corner of the Load window. Also, the name of the current load case has a check mark beside it in the Case menu.  You can set the current load case by choosing the appropriate name from the list of load case names under the Case menu or from the pop-up menu in the Load Case toolbar.

Loads are added by selecting joints or members and choosing the appropriate load command.

You can delete all the loads from joints or members by selecting the joints or members and pressing the Delete key.
