Cone Structure 
Namespace: Rhino.Geometry
The Cone type exposes the following members.
Name  Description  

ApexPoint  Point at tip of the cone.  
Axis  Unit vector axis of cone.  
BasePoint  Center of base circle.  
Height 
Gets or sets the height of the circular right cone.
 
IsValid 
true if plane is valid, height is not zero and radius is not zero.
 
Plane 
Gets or sets the base plane of the cone. The apex of the cone is at the plane's origin.
 
Radius 
Gets or sets the radius of the cone.
 
Unset 
Gets an invalid Cone.

Name  Description  

AngleInDegrees 
Computes the angle (in degrees) between the axis and the
side of the cone.
The angle and the height have the same sign.
 
AngleInRadians 
Computes the angle (in radians) between the axis and the
side of the cone.
The angle and the height have the same sign.
 
EpsilonEquals 
Check that all values in other are within epsilon of the values in this
 
Equals  Indicates whether this instance and a specified object are equal. (Inherited from ValueType.)  
GetHashCode  Returns the hash code for this instance. (Inherited from ValueType.)  
GetType  Gets the Type of the current instance. (Inherited from Object.)  
ToBrep 
Gets a Brep representation of the cone with a single
face for the cone, an edge along the cone seam,
and vertices at the base and apex ends of this seam edge.
The optional cap is a single face with one circular edge
starting and ending at the base vertex.
 
ToNurbsSurface 
Constructs a Nurbs surface representation of this Cone.
This is synonymous with calling NurbsSurface.CreateFromCone().
 
ToRevSurface 
Constructs a RevSurface representation of this Cone.
This is synonymous with calling RevSurface.CreateFromCone().
 
ToString  Returns the fully qualified type name of this instance. (Inherited from ValueType.)
