Purges the fit data of a spline.
Supported platforms: Windows only
No return value.
Removes the fit data of a spline.
VBA:
Sub Example_PurgeFitData()
' This example creates a spline object in model space.
' It then returns the current number of fit points,
' and then purges the fit data.
Dim splineObj As AcadSpline

fitPoints(6) = 10: fitPoints(7) = 0: fitPoints(8) = 0
