I need to export coordinates of 3D Streamlines to a CSV file so that i can make a CAD model of the flow pattern past a conical shock wave.
please help.

I am working on a project where i have to generate a waverider configuration from a conical shock wave for a given Mach number and generating cone angle. as the streamlines past a conical shock wave curves and follows taylor-maccoll equations, the streamlines generated from a plane which cuts the conical shock wave but not the generating cone, gives a set of streamlines which are coming out of the aforementioned plane. these streamlines which are emanating from parabola on the surface of the conical shockwave, are forming the geometry of the required Waverider Configuration.

I want to make a CAD model of the waverider thus formed so that i can further perform aerodynamic analysis. for that i have exported the streamline data from FILE>EXPORT>Streamline> and chosen the x,y and z coordinates as my export variables to .csv file.
but now that i am plotting this so obtained coordinates in MATLAB, i am getting some absurd geometry.

Please help!!!
i need to build a CAD model of the waverider in CATIA or the design modular from the data obtained by coordinates of streamlines past the conical shock wave.

If possible, you could export the data to the Ensight Gold format and perform the postprocessing in ParaView. I've explained a simple strategy in one of my ParaView videos:
