Vector3D vector1 = new Vector3D(20, 30, 40);
Double length;

length = vector1.Length;
// length is approximately equal to 53.85165

' Gets the length of a Vector3D.  
' Returns a Double.

Dim vector1 As New Vector3D(20, 30, 40)
Dim length As Double

length = vector1.Length
' length is approximately equal to 53.85165
