surface body is wider and longer than the faces you are replacing.
Click Replace Face 
on the Surfaces
toolbar, or click Insert, Face, Replace.
In the
PropertyManager, under Replace Parameters:
Select
the faces to replace for Target faces
. The faces must be connected but they do not have to
be tangent.

the replacement surface for Replacement
surfaces 
.
-
Click OK

The faces are replaced with
the surface and the adjacent faces of the original body are trimmed and
extended to fit. The new face is trimmed to fit the adjacent faces of
the original body.
