In RFEM and RSTAB, it is possible to define various cross-sections for a member start and a member end. Hinges, eccentricities and member divisions can also be related to both the member start and the member end. Therefore, it is important to know where are the member start and the member end located.
You can show or hide the display of the member orientation in Project Navigator - Display (see the figure).
If it is necessary to change the direction of a member, the orientation can be reversed by right-clicking the member and using the corresponding option in the shortcut menu.
