Create an Edge-Defined 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, or elliptical arcs that 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 ruled mesh
1 Click Home tab ➤ Modeling panel ➤ Ruled Surface.
2 Select an object to act as the first defining curve.
3 Select a second object as the second defining curve.
Mesh segments are drawn between the defining curves. The number of
segments equals the value set for SURFTAB1.
4 Erase the original curves if necessary.
To create a tabulated mesh
1 Click Home tab ➤ Modeling panel ➤ Tabulated Surface.
2 Specify an object to define the overall shape of the tabulated surface (the
path curve).
The object can be a line, arc, circle, ellipse, or a 2D or 3D polyline.
3 Specify an open line or polyline that defines the direction vector.
The mesh is extended from the start point to the endpoint of the direction
vector.
4 Erase the original objects if necessary.
