Cubic-Spline Curve Extraction from CAD with Zero Chord Tolerance

Hello All,

I have a CAD file with Class A surfaces, and the curve on the edges are C2 continuous. However, when I'm extracting the curve (0.1mm split distance) to a .csv file and plotted out, the curve consists of several straight line segments rather than a single cubic spline. 

Is there a way to extract the curve finely with zero chord tolerance? I'm not seeing any settings for curve extraction besides split distance.

No there's no way to do that, and even if it was the case, how would you transfer that to the robot?
Robot controllers only understand linear motions.

Some do understand spline, but it's still based on small linear motion and you can't know for sure what will be the final path.
