Gets the fit point of a spline at a given index.
Supported platforms: Windows only
VBA:
RetVal = object.GetFitPoint(Index)
Type: Spline
The object this method applies to.
Access: Input-only
Type: Long
The position in the fit point list at which to query the fit point. The index must be a positive integer beginning with 0.
Type: Variant (three-element array of doubles)
The 3D WCS coordinates of the fit point at the given index location.
No additional remarks.
