SetFitPoint Method (ActiveX)

Sets a fit point for the spline.

Supported platforms: Windows only

Signature

VBA:

object.SetFitPoint Index, Value

object

Type: Spline

The object this method applies to.

Index

Access: Input-only

Type: Long

The index location of the fit point you wish to set. The first fit point is index 0.

Value

Type: Variant (three-element array of doubles)

The 3D WCS coordinates specifying the fit point for the spline at the given index location.

Return Value (RetVal)

No return value.

Remarks

No additional remarks.

Examples

VBA:

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

    ' Create the spline

    Dim endTan(0 To 2) As Double

    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)
