Toolbar: Draw 3D > Cone ()

Menu: Insert > 3D Entities > Cone

Keyboard: CONE

Alias: AI_CONE

Experience Level: Intermediate

Draws a three-dimensional cone, with a circular or elliptical cone and a symmetrical or offset tip.

Type cone to create a three-dimensional ACIS solid; type ai_cone to create a three-dimensional surface.


  1. Specify the radius of the base of the cone by selecting two points.
  2. Specify the height of the cone by selecting two points.

Elliptical Divisions <Center of base of cone> <value>: Specify the center point of the base of the cone. For a cone with an elliptical base, choose Elliptical. To specify the number of divisions (tessellation lines that define the surface of the cone), choose Divisions.

Diameter <Radius of base>: Enter the radius of the base of the cone, or specify a second point to indicate the radius. To specify the diameter of the base, choose Diameter and then enter the diameter or specify two points.

Apex <Height of cone>: Enter the height of the cone or specify two points. For a cone with an offset top, choose Apex.

To specify the number of divisions

Choose Divisions.

Number of Divisions <value>: Specify the number of divisions, usually between 4 and 20. A large number of divisions slows the program considerably. A small number of divisions makes the cone unrecognizable.

To draw a cone with an elliptical base

Choose Elliptical.

Center <First end of ellipse axis>: Specify the first end of an ellipse representing the base of the cone. This ellipse is drawn based on the length of one axis and the half-length of the second axis. To draw the elliptical base based on a center point and the endpoints of the minor and major axes, choose Center.

To draw a cone with an apex tip

Choose Apex.

Apex of cone: Specify a point for the apex (tip) of the cone.
