Length and Normalized Arc Length Point

I tried to link some of my old code which depended on previous version of OpenNURBS with the recently available one. I find that the methods GetLength() and Get NormalizedArcLengthPoint() methods are not defined for ON_NurbsCurve()

Please let me know how I should go about to get Length and NormalizedArcLengthPoint for NurbsCurve.

Thanks in advance.

With best regards,

Hi Partha,

These members are not longer available in the free openNURBS toolkit. But, they are available in the Rhino SDK.

Why do you need these methods to read and/or write Rhino files?


I recently started to study the Nurbs function.
The OpenNurbs are very useful for studying Nurbs function and Topology.
Therefore I cafully read the your online manual and source.
I recently knew the status of GetLength and NormalizedArcLength etc.
But I think that is it better to remove online manual for this functions.
I am some confusing in some times.

Best Regards

Hi @junghwan.jeong,

The online API that you are referring to is for the Rhino C++ SDK, which includes openNURBS. It is not for the standalone version of openNURBS.
