To Create a Surface by Revolution

Select the Surface by Revolution tool ( Drawing > Surfaces > Create Surfaces > Revolve Surface > Revolve ).
To create a parametric surface, turn on Parametric.
Note: Creating a parametric surface is the ideal thing to do, as it will let you edit it easily without needing to be manually rebuilt.
(Optional) In the Angle field, type the required value or use Variable link to set it from the available variables in the Variables dialog.
Select the profile element.
Enter a data point. Use AccuDraw to ensure the axis of revolution is defined at the exact location desired.
If Axis is set to Points, this data point defines one point on the axis of revolution. Otherwise, this data point defines the axis of revolution.
If Axis is set to Points, enter a second data point to define another point on the axis of revolution.
