exporting contour results into PDF vector format.

Hello all,

I read plenty of feeds regarding exporting of the model/ assembly file into vector format for high resolution (Saving as PDF of AI). But It seems we can't do such for the contour results. Saving image/ cropping all produced the pixelated image. I have the following 2D contour but I only want to export it's isolines in high resolution vector format to be editable in adobe illustrator. Is there a way? Please help

When I save it as pdf or ai file, the contour/ isolines disappeared
