Represents a surface geometry type that is defined by a control net, crease information and a refinement level. This is often called a subdivision surface.

Public Class SubD
	Inherits GeometryBase

The SubD type exposes the following members.

	Name	Description
	SubD	Initializes a new empty SubD surface.

	Name	Description
	ActiveLevel
	ActiveLevelSubDType
	Edges	Gets access to edges.
	Faces	Gets access to faces.
	HasBrepForm	Returns true if the Brep.TryConvertBrep function will be successful for this object (Inherited from GeometryBase.)
	IsDeformable	true if object can be accurately modified with "squishy" transformations like projections, shears, and non-uniform scaling. (Inherited from GeometryBase.)
	IsDocumentControlled	If true this object may not be modified. Any properties or functions that attempt to modify this object when it is set to "IsReadOnly" will throw a NotSupportedException. (Inherited from GeometryBase.)
	Level
	ObjectType	Useful for switch statements that need to differentiate between basic object types like points, curves, surfaces, and so on. (Inherited from GeometryBase.)
	UserStringCount	Gets the amount of user strings. (Inherited from GeometryBase.)
	Vertices	Gets access to vertices.

	Name	Description
	ChamferVertex	Removes a vertex and inserts a face using some parameters.
	ComponentIndex	If this piece of geometry is a component in something larger, like a BrepEdge in a Brep, then this function returns the component index. (Inherited from GeometryBase.)
	CreateFromMesh
	Dispose	Releases the unmanaged resources used by the SubD and optionally releases the managed resources (Overrides GeometryBase.Dispose(Boolean).)
	Duplicate	Constructs a deep (full) copy of this object. (Inherited from GeometryBase.)
	DuplicateShallow	Constructs a light copy of this object. By "light", it is meant that the same underlying data is used until something is done to attempt to change it. For example, you could have a shallow copy of a very heavy mesh object and the same underlying data will be used when doing things like inspecting the number of faces on the mesh. If you modify the location of one of the mesh vertices, the shallow copy will create a full duplicate of the underlying mesh data and the shallow copy will become a deep copy. (Inherited from GeometryBase.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetBoundingBox(Boolean)	Boundingbox solver. Gets the world axis aligned boundingbox for the geometry. (Inherited from GeometryBase.)
	GetBoundingBox(Plane)	Aligned Boundingbox solver. Gets the plane aligned boundingbox. (Inherited from GeometryBase.)
	GetBoundingBox(Transform)	Aligned Boundingbox solver. Gets the world axis aligned boundingbox for the transformed geometry. (Inherited from GeometryBase.)
	GetBoundingBox(Plane, Box)	Aligned Boundingbox solver. Gets the plane aligned boundingbox. (Inherited from GeometryBase.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetLimitSurfaceInPatches
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetUserString	Gets user string from this geometry. (Inherited from GeometryBase.)
	GetUserStrings	Gets a copy of all (user key string, user value string) pairs attached to this geometry. (Inherited from GeometryBase.)
	MakeDeformable	If possible, converts the object into a form that can be accurately modified with "squishy" transformations like projections, shears, an non-uniform scaling. (Inherited from GeometryBase.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemoryEstimate	Computes an estimate of the number of bytes that this object is using in memory. (Inherited from GeometryBase.)
	NonConstOperation	Destroy cache handle (Inherited from GeometryBase.)
	OnSwitchToNonConst	(Overrides GeometryBase.OnSwitchToNonConst().)
	Rotate	Rotates the object about the specified axis. A positive rotation angle results in a counter-clockwise rotation about the axis (right hand rule). (Inherited from GeometryBase.)
	Scale	Scales the object by the specified factor. The scale is centered at the origin. (Inherited from GeometryBase.)
	SetSubDType
	SetUserString	Attach a user string (key,value combination) to this geometry. (Inherited from GeometryBase.)
	Subdivide(Int32, SubD.SubDType, Int32)
	Subdivide(Int32, SubD.SubDType, Int32, Int32)
	SubDTypeFromInt
	ToLimitSurfaceMesh(Int32)
	ToLimitSurfaceMesh(SubDDisplayParameters)
	ToLimitSurfaceMesh(Int32, SubD.SubDType)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Transform	Transforms the geometry. If the input Transform has a SimilarityType of OrientationReversing, you may want to consider flipping the transformed geometry after calling this function when it makes sense. For example, you may want to call Flip() on a Brep after transforming it. (Inherited from GeometryBase.)
	Translate(Vector3d)	Translates the object along the specified vector. (Inherited from GeometryBase.)
	Translate(Double, Double, Double)	Translates the object along the specified vector. (Inherited from GeometryBase.)
