Creates a three-dimensional polygon 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. You can use the SURFTAB2
system variable to define the N-direction mesh density of the revolved surface.
- Select the entity to revolve.
- Select the axis around which the entity revolves.
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 <0º>: 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°.
