Create it using a CSG of either cylinders and spheres or thin boxes
depending on the look you want.

What kind of surface?  The surface needs to intersect the box for this to
work and the surface to be visible.   If the surface lies above the top
face of the box, then an intersection will create only the same box, as the
second surface would lie outside the physical intersection and not have an
effect.
