Create an Edge-Defined Surface Mesh
With the
EDGESURF command, you can create a Coons surface patch mesh, as
shown in the following illustration, from four objects called edges. Edges can
be arcs, lines, polylines, splines, and elliptical arcs, and they must form a
closed loop and share endpoints. A Coons patch is a bicubic surface (one
curve in the M direction and another in the N direction) interpolated
between the four edges.
To create a rectangular mesh
1 From the Draw menu, choose Surfaces ➤ 3D Mesh.
2 Specify the M size, using an integer from 2 through 256.
3 Specify the N size, using an integer from 2 through 256.
4 Specify the vertex points as prompted. Specifying the last vertex point
completes the mesh.
