Reverse Node Order for Selected Elements

Modify > Reverse Node Order for Selected Elements allows you to reverse the nodes’ order for selected elements.  For members and shells, this command in effect changes their local coordinate systems.  For bricks, this command may be used to rectify a wrong nodal ordering which results in negative diagonals in element stiffness.

It is important to point out that dependents on the elements are not reversed or changed accordingly.  After running this command, you should check on these dependents such as loads and moment releases on members, loads on shells, etc.
