Gets the degree of the spline's polynomial representation.
Supported platforms: Windows only
Read-only: Yes
Type: Integer
An integer between 1 and 25 inclusive.
The order of the spline is equal to the degree of the spline plus one (+1).
VBA:
Sub Example_Degree()
' This example creates a spline and returns the degree
' of the spline's polynomial representation.
Dim splineObj As AcadSpline

fitPoints(6) = 10: fitPoints(7) = 0: fitPoints(8) = 0
Set splineObj = ThisDrawing.ModelSpace.AddSpline(fitPoints, startTan, endTan)
