3D Commands - CONE

Creates a 3D solid cone.

 Find

Creates a 3D solid with a circular or elliptical base that tapers symmetrically to a point or to a circular or elliptical planar face. You can control the smoothness of 3D curved solids, such as a cone, in a shaded or hidden visual style with the FACETRES system variable.

Use the Top Radius option to create a cone frustum.

Initially, the default base radius is not set to any value. During a drawing session, the default value for the base radius is always the previously entered base radius value for any solid primitive.

The following prompts are displayed.

Center Point of Base

2Point

Specifies that the height of the cone is the distance between the two specified points.

Axis Endpoint

Specifies the endpoint location for the cone axis. The axis endpoint is the top point of the cone or the center point of the top face of the cone frustum (Top Radius option). The axis endpoint can be located anywhere in 3D space. The axis endpoint defines the length and orientation of the cone.

Top Radius

Specifies the top radius of the cone, creating a cone frustum.

Initially, the default top radius is not set to any value. During a drawing session, the default value for the top radius is always the previously entered top radius value for any solid primitive.

Diameter

Specifies the diameter for the base of the cone.

Initially, the default diameter is not set to any value. During a drawing session, the default value for the diameter is always the previously entered diameter value for any solid primitive.

3P (Three Points)

Defines the base circumference and base plane of the cone by specifying three points.

Additional prompts include

• 2Point
• Axis Endpoint
• Top Radius

2P (Two Points)

Defines the base diameter of the cone by specifying two points.

Additional prompts include

• 2Point
• Axis Endpoint
• Top Radius

TTR (Tangent, Tangent, Radius)

Defines the base of the cone with a specified radius tangent to two objects.

Sometimes, more than one base matches the specified criteria. The program draws the base of the specified radius whose tangent points are closest to the selected points.

Additional prompts include

• 2Point
• Axis Endpoint
• Top Radius

Elliptical

Specifies an elliptical base for the cone.

Center

Creates the base of the cone by using a specified center point.

Additional prompts include

• 2Point
• Axis Endpoint
• Top Radius
