NumberOfControlPoints Example

Using Programming Languages other than VBA

Sub Example_NumberOfControlPoints()
	' This example creates a spline object in model space.
	' It then finds the number of control points for that spline.

	' Create the spline
	Dim splineObj As AcadSpline
	Dim startTan(0 To 2) As Double
	Dim endTan(0 To 2) As Double
	Dim fitPoints(0 To 8) As Double

	startTan(0) = 0.5: startTan(1) = 0.5: startTan(2) = 0
	endTan(0) = 0.5: endTan(1) = 0.5: endTan(2) = 0
	fitPoints(0) = 1: fitPoints(1) = 1: fitPoints(2) = 0
	fitPoints(3) = 5: fitPoints(4) = 5: fitPoints(5) = 0
	fitPoints(6) = 10: fitPoints(7) = 0: fitPoints(8) = 0
	Set splineObj = ThisDrawing.ModelSpace.AddSpline(fitPoints, startTan, endTan)
	ZoomAll

	MsgBox "The Spline has " & splineObj.NumberOfControlPoints & " control points.", , "NumberOfControlPoints Example"

End Sub
