Creates a mesh between four contiguous edges or curves.
Tool Set:
.
Menu: .
Select four adjoining edges that define the mesh. The edges can be lines, arcs, splines, or open polylines. The edges must touch at their endpoints to form a single, closed loop.
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.

The MESHTYPE system variable sets which type of mesh is created. Mesh objects are created by default. Set the variable to 0 to create legacy polyface or polygon mesh.
The following prompts are displayed.
Specifies the first edge to be used as a boundary.
Specifies the second edge to be used as a boundary.
Specifies the third edge to be used as a boundary.
Specifies the final edge to be used as a boundary.
