Syntax

public class ConicalSurface : Surface

The ConicalSurface type exposes the following members.

Properties

Name

Description

Public Property

Axis

Axis of the cone. This is the Z axis of the local coordinate system associated with this cone.

Public Property

HalfAngle

Cone angle.

Public Property
IsValidObject

Specifies whether the .NET object represents a valid Revit entity.
(Inherited from Surface)

Public Property
OrientationMatchesParametricOrientation

Indicates whether this Surface’s orientation is the same as or opposite to its parametric orientation.
(Inherited from Surface)

Public Property

Origin

Apex of the cone. This is the origin of the local coordinate system associated with this cone.

Public Property

XDir

X axis of the local coordinate system associated with this cone.

Public Property

YDir

X axis of the local coordinate system associated with this cone.

Methods

Name

Description

Public Method
Static Member
Create

Creates a conical surface defined by a local reference frame and a half angle.

Public Method

Dispose

(Inherited from Surface)

Public Method

Equals

Determines whether the specified object is equal to the current object.
(Inherited from Object)

Public Method
GetBoundingBoxUV

Gets the UV bounding box of the surface.
(Inherited from Surface)

Public Method
GetFrameOfReference

Returns frame of reference associated with this ConicalSurface.

Public Method

GetHashCode

Serves as the default hash function.
(Inherited from Object)

Public Method

GetType

Gets the Type of the current instance.
(Inherited from Object)

Public Method
Static Member

IsValidConeAngle

Checks whether the input value lies is not 0, greater than -PI/2 and lesser than PI/2.

Public Method

Project

Project a 3D point orthogonally onto a surface (to find the nearest point). Throws InvalidOperationException if the projection fails.
(Inherited from Surface)

Public Method

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)

Public Method

ToString

Returns a string that represents the current object.
(Inherited from Object)

Remarks

The parametric equation of the cone is S(u, v) = center + v*[sin(halfAngle)(cos(u)*xVec + sin(u)*yVec) + cos(halfAngle)*zVec]. Only the branch of the cone with v >= 0 should be used.
