Select object 1 for surface edge:
Select object 2 for surface edge:
Select object 3 for surface edge:
Select object 4 for surface edge:
You must select the four adjoining edges that define the surface patch. The
edges can be lines, arcs, splines, or open 2D or 3D polylines. The edges must
touch at their endpoints to form a topologically rectangular closed path.
You can select the four edges in any order. The first edge (SURFTAB1)
determines the M direction of the generated mesh, which extends from the
endpoint closest to the selection point to the other end. The two edges that
touch the first edge form the N edges (SURFTAB2) of the mesh.

ELEV
Sets elevation and extrusion thickness of new objects
Command line: elev (or 'elev for transparent use)
Specify new default elevation <current>: Specify a distance or press ENTER
The current elevation is the default Z value for new objects when you specify
only X and Y values for a 3D point.
The elevation setting is the same for all viewports regardless of their user
coordinate systems (UCSs). New objects are created at the specified Z value
relative to the current UCS in the viewport.
