Create a Solid Cone

Create a pointed or frustum of a cone with a circular or elliptical base.

By default, the base of the cone lies on the XY plane of the current UCS. The height of the cone is parallel to the Z axis.

Cone Creation Options

Use the following options to control the size and rotation of the cones you create:

Set the height and orientation. Use the Axis Endpoint option of the CONE command. Use the Top Radius option to specify the axis endpoint as the point of the cone or the center of the top face. The axis endpoint can be located anywhere in 3D space.
Create a frustum of a cone. Use the Top Radius option of the CONE command to create a frustum, which tapers to an elliptical or planar face.

The Frustum tool is also available from the Modeling tab of the tool palette. You can also use grips to modify the tip of a cone and convert it to a flat face.
Specify circumference and base plane. The 3P (Three Points) option of the CONE command defines the size and plane of the base of the cone anywhere in 3D space.
Define the angle of the taper. To create a conical solid that requires a specific angle to define its sides, draw a 2D circle. Then use EXTRUDE and the Taper Angle option to taper the circle at an angle along the Z axis. This method, however, creates an extruded solid, not a true solid cone primitive.
