Sculpting with both Z and X axis symmetry? Pretty simple question, i would really like to sculpt some pillars that are symmetrical on both the x and z axis, is there any way at all to enable this in blender? or is there a way to make a model symmetrical along both the x and z axis once modelled?

Thanks in advance!
Yes: 2.7:

or 2.8:



Also, once modeled, you can delete some parts and add a mirror modifier, which can work on X and Z (Pivot point of mirroring is the origin of the object).
