IsPeriodic Example

Using Programming Languages other than VBA

Sub Example_IsPeriodic()
   ' This example creates a Spline object in model space and
   ' determines if the Spline is periodic

	Dim splineObj As AcadSpline
	Dim startTan(0 To 2) As Double, endTan(0 To 2) As Double
	Dim fitPoints(0 To 8) As Double
	Dim UserMessage As String

	' Define the Spline object
	startTan(0) = 0.5: startTan(1) = 0.5: startTan(2) = 0
	endTan(0) = 0.5: endTan(1) = 0.5: endTan(2) = 0
	fitPoints(0) = 0: fitPoints(1) = 0: fitPoints(2) = 0: fitPoints(3) = 5
	fitPoints(4) = 5: fitPoints(5) = 0: fitPoints(6) = 10: fitPoints(7) = 0: fitPoints(8) = 0

	' Create new Spline object
	Set splineObj = ThisDrawing.ModelSpace.AddSpline(fitPoints, startTan, endTan)

	' Display whether or not new Spline is periodic
	UserMessage = IIf(splineObj.IsPeriodic, "is periodic", "is not periodic")

	MsgBox "The new Spline " & UserMessage
