Conical | 
The ConicalSurface type exposes the following members.
| Name | Description | |
|---|---|---|
| Axis | Axis of the cone. This is the Z axis of the local coordinate system associated with this cone. | |
| HalfAngle | Cone angle. | |
| IsValidObject | 
   Specifies whether the .NET object represents a valid Revit entity.
 (Inherited from Surface)  | |
| OrientationMatchesParametricOrientation | 
   Indicates whether this Surface's orientation is the same as or opposite to its parametric orientation.
 (Inherited from Surface)  | |
| Origin | Apex of the cone. This is the origin of the local coordinate system associated with this cone. | |
| XDir | X axis of the local coordinate system associated with this cone. | |
| YDir | X axis of the local coordinate system associated with this cone. | 
| Name | Description | |
|---|---|---|
| Create | Creates a conical surface defined by a local reference frame and a half angle. | |
| Dispose | (Inherited from Surface)  | |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object)  | |
| GetBoundingBoxUV | 
   Gets the UV bounding box of the surface.
 (Inherited from Surface)  | |
| GetFrameOfReference | Returns frame of reference associated with this ConicalSurface. | |
| GetHashCode | Serves as the default hash function. (Inherited from Object)  | |
| GetType | Gets the Type of the current instance. (Inherited from Object)  | |
| IsValidConeAngle | Checks whether the input value lies is not 0, greater than -PI/2 and lesser than PI/2. | |
| Project | 
   Project a 3D point orthogonally onto a surface (to find the nearest point).
   Throws InvalidOperationException if the projection fails.
 (Inherited from Surface)  | |
| ProjectWithGuessPoint | 
   Project a 3D point orthogonally onto a surface (to find the nearest point).
   This method is meant to be used when a good approximate solution for the projection is available.
   Throws InvalidOperationException if the projection fails.
 (Inherited from Surface)  | |
| ToString | Returns a string that represents the current object. (Inherited from Object)  |
