A traveller can wander ZBrush for years and consistently find new avenues to explore.
One such surprise for me was to use the Gizmo on a mesh with > Bend Curve + > Transform >Activate Symmetry set to radial on the Y axis - doing so allowed for quick circular array effects.
Moving the mesh upwards (to place it’s pivot lower) and then > Bend Curve with Transform >Activate Symmetry set to Y axis (with or without Radial array) will mirror the mesh on the Y.
To test this constructively I used a simple cylinder as the starting point for the image posted above and here .
