A DPoint3d is defined by x, y, z coordinates. It can be created in the following ways using constructors.

	DPoint3d ptD3d;
	nt3d ptD3d = new DPoint3d();
	DPoint3d ptD3d = new DPoint3d(ref DPoint2d Source); 
	DPoint3d ptD3d = new DPoint3d(ref DVector2d Source); 
	DPoint3d ptD3d = new DPoint3d(ref DPoint3d Source);
	DPoint3d ptD3d = new DPoint3d(ref DVector3d Source);
	DPoint3d ptD3d = new DPoint3d(double ax, double ay);
	DPoint3d ptD3d = new DPoint3d(double ax, double ay,
double az);

DPoint3d's can also be Initialized using .Init

	ptD3d.Init(ref DPoint2d Source);
	ptD3d.Init(ref DVector2d Source);
	ptD3d.Init(ref DPoint3d Source);
	ptD3d.Init(ref DVector3d Source);
	ptD3d.Init(double ax, double ay);
	ptD3d.Init(double ax, double ay, double az);

DPoint3d can also have their values specified individually:

	ptD3d.X = 5.0;
	ptD3d.Y = 4.6;
	ptD3d.Z = 2.3;

In Place addition and subtraction

	Distance(ref DPoint3d Target)
	Eg. pt1D3d.Distance(ref pt2D3d)
