Syntax

public class CylindricalSurface : Surface

Public Class CylindricalSurface
	Inherits Surface

public ref class CylindricalSurface : public Surface

type CylindricalSurface = 
    class
        inherit Surface
    end

The CylindricalSurface type exposes the following members.

Properties

	Name	Description
	Axis	Axis of the cylinder. This is the Z axis of the local coordinate system associated with this cylinder.
	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	Center of the circle that defines the base of the cylinder. This is the origin of the local coordinate system associated with this cylinder.
	Radius	Radius of the circle that defines the base of this cylinder.
	XDir	X axis of the local coordinate system associated with this cylinder.
	YDir	Y axis of the local coordinate system associated with this cylinder.

Methods

	Name	Description
	Create	Construct a cylindrical surface defined by a local coordinate system and a radius.
	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 CylindricalSurface.
	GetHashCode	Serves as the default hash function. (Inherited from Object )
	GetType	Gets the Type of the current instance. (Inherited from Object )
	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 )

Remarks

The parametric equation of the cylinder is S(u, v) = center + radius*cos(u)*xVec + radius*sin(u)*yVec + v*zVec.
