Revolution Tool

Ribbon menu Bodies tab Solids container Revolution Tool
or
(Classic) Build Bodies/Geometry Revolution Tool
Creates geometry by revolving a profile. You specify the profile and the axis about which to revolve the profile. The Revolution tool revolves the profile around the axis in a counterclockwise direction (right-hand rule)
You can create an open or closed revolution. If you create a closed revolution, the Revolution tool closes the profile by drawing a line segment between the profile’s first and last points and creates a solid revolution from this profile. If you leave the revolution open, the Revolution tool creates a skin that has no mass properties.
You can also select to create the revolution using the Non-analytical Method or Analytical Method.
 
For the option:
Do the following:
New Part/Add to Part/On Ground
Select either:
New Part - Creates a new part.
Add to Part - Adds the revolution to another part in your model.
On Ground - Adds the revolution to ground.
Tip: Add geometry to ground if the geometry does not move or influence the simulation of your model. For example, if you are simulating a car driving around a race track, the geometry that defines the race track can be added to ground.
Create by Picking
Select:
Points to select the locations on the screen that define the profile.
Curve to select the curve to be used to define the profile.
Closed
Select to create a closed revolution. (Available only when you set Create by Picking to Points.)
Analytical
Select to create a revolution using the analytical method. Clear to use the non-analytical method
 
Notes:  
After you draw a revolution, hotpoints appear. If you used the non-analytical method to create the revolution, the hotpoints appear at the vertexes of the profile. If you used the analytical method, hotpoints appear at points along the curves that define the revolution. The hotpoints let you resize and reshape the revolution. For more information on modifying geometry using hotpoints, see Using Hotpoints to Graphically Modify Geometry.

You can also use the revolution modify dialog box to more accurately place the points that make up the profile and read in location points from a file. For more information, see Using Dialog Boxes to Precisely Modify Geometry and Using the Location Table.
