Swap Member Ends
The Swap Ends icon lets you swap the start (I-node) and end (J-node) of a member. This can be useful if you are trying to assign connection rules to your members and need to quickly swap columns such that their I-end is at the bottom of the column.

You can also choose to swap the loads with the member ends. If you do not swap the loads, they remain graphically as they are.
