Gets the number of fit points of the spline.
Supported platforms: Windows only
Read-only: Yes
Type: Integer
Number of fit points of the spline.
The fit points define the path of the spline. You can change the tolerance of a given fit point by using the FitTolerance property. You can add a fit point by using the AddFitPoint method. You can delete a fit point by using the DeleteFitPoint method. You can query the location of a fit point by using the GetFitPoint method. You can change the location of a given fit point by using the SetFitPoint method.
VBA:
Sub Example_NumberOfFitPoints()
' This example creates a spline object in model space.
' It then finds the number of control points for that spline.
