Sub Example_BasePoint()
	' This example creates a ray object. It then finds the
	' base point of the ray, changes the base point, and
	' queries the new base point.

	' Create a Ray object in model space
	Set rayObj = ThisDrawing.ModelSpace.AddRay(basePoint, directionVec)

	MsgBox "A new Ray has been added.", vbInformation

	' Define a new base point
	Dim newBase(0 To 2) As Double
