Methods

	Name	Description
	EnsurePrivateCopy	If you want to keep a copy of this class around by holding onto it in a variable after a command completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can call this function as many times as you want.
	EpsilonEquals	Check that all values in other are within epsilon of the values in this
	Equals	(Inherited from Object.)
	GetControlPoint	Gets the control point at the given (u, v) index.
	GetGrevillePoint	Gets the 2-D Greville point associated with the control point at the given (u, v) index.
	GetHashCode	(Inherited from Object.)
	GetPoint(Int32, Int32, Point3d)	Gets a world 3-D, or Euclidean, control point at the given (u, v) index. The 4-D representation is (x, y, z, 1.0).
	GetPoint(Int32, Int32, Point4d)	Gets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).
	GetType	(Inherited from Object.)
	GetWeight	Gets the weight of a control point at the given (u, v) index. Note, if the surface is non-rational, the weight will be 1.0.
	SetControlPoint(Int32, Int32, ControlPoint)	Sets the control point at the given (u, v) index.
	SetControlPoint(Int32, Int32, Point3d)	Sets the control point at the given (u, v) index.
	SetPoint(Int32, Int32, Point3d)	Sets a world 3-D, or Euclidean, control point at the given (u, v) index. The 4-D representation is (x, y, z, 1.0).
	SetPoint(Int32, Int32, Point4d)	Sets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).
	SetPoint(Int32, Int32, Point3d, Double)	Sets a world 3-D, or Euclidean, control point and weight at a given index. The 4-D representation is (xw, yw, z*w, w).
	SetPoint(Int32, Int32, Double, Double, Double)	Sets a world 3-D, or Euclidean, control point at the given (u, v) index. The 4-D representation is (x, y, z, 1.0).
	SetPoint(Int32, Int32, Double, Double, Double, Double)	Sets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).
	SetWeight	Sets the weight of a control point at the given (u, v) index. Note, if the surface is non-rational, it will be converted to rational.
	ToString	(Inherited from Object.)
	ValidateSpacing	Simple check of distance between adjacent control points
