Is it possible to use the symmetry of a symmetric structure to save half of the work load?
In RSTAB and RFEM; it is not possible to use the symmetry of the structure to calculate only half of the system.
It is, however, possible to create only half of the system including the loads and then to generate the other half. To do this, select the entire structure by selecting on the menu "Edit" --> "Select" --> "All." Then select on the menu "Edit" --> "Mirror."
In the "Mirror" dialog box, select the "Create copy" check box. Then click [Details]. In the "Detail Settings for Move/Rotate/Mirror" dialog box, select the "Copy including loading" check box.
In this way, you can also omit the supports in the mirror axis and obtain more realistic results.
