To create a tabulated surface mesh
1 From the Draw menu, choose Surfaces ➤ Tabulated Surface.
2 Specify a path curve.
3 Specify a direction vector.
4 Erase the original objects if necessary.

To create a surface of revolution mesh
1 From the Draw menu, choose Surfaces ➤ Revolved Surface.
2 Specify a path curve.
The path curve, which defines the N direction of the mesh, can be a line,
arc, circle, ellipse, elliptical arc, 2D polyline, 3D polyline, or spline. If you
select a circle, closed ellipse, or closed polyline, AutoCAD closes the mesh
in the N direction.
3 Specify the axis of revolution.
The direction vector can be a line or an open 2D or 3D polyline. If you
choose a polyline, the vector sets the rotation axis from its first vertex to
its last vertex. AutoCAD ignores any intermediate vertices. The axis of
revolution determines the M direction of the mesh.
4 Specify the start angle. Then specify the included angle.
If you specify a nonzero start angle, AutoCAD generates the mesh at a
position offset from the path curve by that angle. The included angle
specifies how far about the axis of revolution the surface should extend.
5 Erase the original objects if necessary.

To create an edge-defined Coons surface patch mesh
1 From the Draw menu, choose Surfaces ➤ Edge Surface.
2 Select the four edges in any order.
The first edge you select determines the mesh’s M direction.
