Since the forces and moments always affect an object/volume they must be adjusted. If only considering half the part, the forces and moments need to be divided in half as well.

The symmtery constraint might not show exactly symmetrical designs while choosing the calculation type “estimate”. This is because of the low resolution level but will not occur once the calculation type is set to “optimizing” and the optimization runs through.
Further information symmetry function is an unsupported feature in the MSC Apex Generative Design 2020 Release but can be activated using the Advanced User Settings. Therefore, a few requirements are necessary. Further information regarding the background of the symmetry function can be found here and a Tutorial for a symmetrical optimisation here.
