Revolved Surface
()
Keyboard: REVSURF
Creates a three-dimensional mesh that approximates a surface of revolution by rotating a curve around an axis. The curve sweeps around the selected axis to define the surface in the N direction of the mesh. To close the mesh in the N direction, select a circle or closed polyline as the curve.
If you select a polyline, the vector from the first vertex to the last determines the rotation axis. All other vertices are ignored. The M direction of the mesh is determined by the axis of revolution.

Select a linear entity to revolve: Select a line, arc, circle, or polyline.
Select the axis of revolution: Select a line or open polyline.
Angle to begin surface of revolution <0>: To accept the current setting, press Enter, or enter a new value. When you specify an angle, the surface of revolution begins at an offset from the generated curve path.
Degrees to revolve entity (+ for ccw, - for cw) <360>: To accept the current setting, press Enter, or enter a new value. To prevent the circle from closing, enter a value of less than 360°.
NOTE You can change the M- and N-mesh densities with the SURFTAB1 and SURFTAB2 system variables, respectively.
By default, a mesh entity is created. Set the MESHTYPE system variable to 0 to create a legacy polygon or polyface mesh.
