Answer:
In the "Edit Nodal Supports" dialog box, it is possible to rotate the local axis system of the support (Image 01). First, select the sequence that controls the sequence of the local support axes X', Y', and Z', then specify the rotation angle about the global axes X, Y, and Z in the corresponding text boxes.
The support rotation can also be determined graphically using the corresponding buttons in the dialog box. The rotation of the support is displayed dynamically in the dialog graphic.
After the calculation, the support reactions of the rotated nodal support can be evaluated both on the global axis system and the local axis system (Image 02).
