Sub Example_ModelSpace()
	' This example adds a line and a circle to model space.
	' The line is added using a user-defined variable representing
	' the model space. The circle is added without using the
	' user-defined variable. Either use of the ModelSpace
	' property is valid.

	' Define the line
	Dim lineObj As AcadLine
	Dim startPoint(0 To 2) As Double
	Dim endPoint(0 To 2) As Double
	startPoint(0) = 0: startPoint(1) = 0: startPoint(2) = 0
	endPoint(0) = 4: endPoint(1) = 4: endPoint(2) = 0

	' Add the line to model space using the mspace variable
	Dim mspace As AcadModelSpace
	Set mspace = ThisDrawing.ModelSpace
	Set lineObj = mspace.AddLine(startPoint, endPoint)

	' Define a circle
	Dim circleObj As AcadCircle
	Dim center(0 To 2) As Double
	Dim radius As Double
	center(0) = 4: center(1) = 4: center(2) = 0
	radius = 1

	' Add the circle to model space without using the mspace variable
	Set circleObj = ThisDrawing.ModelSpace.AddCircle(center, radius)
