I guess you’re looking for shell command:

Join the surfaces into a single polysurface.
OffsetSrf the polysurface with the desired thickness.
The result will be a polysurface spaced the desired thickness from the input polysurface.

Rhino models surfaces, not volumes. A solid in Rhino is modeled as a closed surface/polysurface with no naked edges. A naked edge is an edge of a surface or polysurface which is not joined to another edge. This means that the two polysurfaces will be independent.

One way to create a single volume is to create a hole connecting the two polysurfaces. This is what the Shell command does.

What will the offset surface be used for?
