To Revolve Objects About an Axis to Create a NURBS Surface

1. Click Modeling tab > Solid panel > Modeling drop-down > Revolve.
2. Select the objects or edge subobjects to revolve.
3. To set the axis of revolution, specify one of the following:
   • The start and endpoint. Click to points on the screen to set the axis orientation. The axis points must be on one side of the revolved object. The positive axis direction extends from the start point to the endpoint.
   • The X, Y, or Z axis. Enter x, y, or z.
   • An object. Select a line, a linear edge of a polyline segment, or the linear edge of a surface or solid.
4. Specify the angle of revolution by entering a value or dragging the endpoint.
