GetWeight Example

Using Programming Languages other than VBA

Sub Example_GetWeight()
	' This example creates a spline object in model space.
	' It then finds the weight of the first control point
	' and changes that value.

	' 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

	' Display the coordinates of the first fit point
	Dim weight As Double
	weight = splineObj.GetWeight(0)
	MsgBox "The weight of control point 1 is " & weight, , "GetWeight Example"

	' Change the weight of the first control point
	weight = 5
	splineObj.SetWeight 0, weight
	splineObj.Update
	MsgBox "The weight of control point 1 is now " & weight, , "GetWeight Example"

End Sub
