Create a Solid or Surface by Revolving
Create a 3D object by revolving curves about an axis.
When the Mode option is set to Surface, you will create a surface and if Mode
is set to Solid you will create a solid regardless of whether the curve is open
or closed. See
Overview of Creating Solids and Surfaces (page 342) for more
information. When revolving a solid, you can only use a revolve angle of 360
degrees.
Options for Revolving
Mode. Sets whether the revolve creates a surface or a solid.
Start Angle. Specifies an offset for the revolution from the plane of the
object being revolved.
Reverse. Changes the direction of the revolve.
Expression. Enter a formula or equation to specify the revolve angle.
This option is only available if you are creating associative surfaces. See
Create Geometric Relationships between Associative Surfaces (page 381).

Create Solids
Create 3D solids from primitives or by combining or extending existing objects.
Overview of Creating 3D Solids
3D solid objects often start as one of several basic shapes, or primitives, that
you can then modify and recombine. A 3D solid can also be the result of
extruding a 2D shape to follow a specified path in 3D space.
