public class Surface : IDisposable

The Surface type exposes the following members.

	Name	Description
	IsValidObject	Specifies whether the .NET object represents a valid Revit entity.
	OrientationMatchesParametricOrientation	Indicates whether this Surface's orientation is the same as or opposite to its parametric orientation.

	Name	Description
	Dispose	Releases all resources used by the 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.
	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.
	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.
	ToString	Returns a string that represents the current object. (Inherited from Object)

This geometric object is not bounded by edges or edge loops. A bounded surface obtained from a Revit element will be represented by a Face instead.
