The Plane type exposes the following members.

Methods

	Name	Description
	Create	Creates a Plane object defined by a local frame of reference.
	CreateByNormalAndOrigin	Constructs a Plane object from a normal and an origin represented as XYZ objects. Follows the standard conventions for a planar surface. The constructed Plane object will pass through origin and be perpendicular to normal. The X and Y axes of the plane will be defined arbitrarily.
	CreateByOriginAndBasis	Creates a Plane object defined by the two orthogonal unit vectors and passing through the origin point supplied as arguments.
	CreateByThreePoints	Creates a Plane object passing through three points supplied as arguments.
	Dispose	(Inherited from Surface .)
	Equals	Determines whether the specified Object is equal to the current Object . (Inherited from Object .)
	GetHashCode	Serves as a hash function for a particular type. (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 .)

Properties

	Name	Description
	IsValidObject	Specifies whether the .NET object represents a valid Revit entity. (Inherited from Surface .)
	Normal	Plane normal.
	OrientationMatchesParametricOrientation	Indicates whether this Surface's orientation is the same as or opposite to its parametric orientation. (Inherited from Surface .)
	Origin	Plane origin.
	XVec	Axis defining the first parametric direction of the plane.
	YVec	Axis defining the second parametric direction of the plane.
