Does anyone know how to convert a 3D model back into a 2D sketch so I can review the coordinates for a parabola?

Hi,

Basically I have saved a group of models in the native solidworks file format which have been machined into metal models. However it has come to my attention that there may be an error in a few of them. Does anyone know if there is a way to retrieve coordinates for parabolic arches once it has been converted into a 3D model and saved? I have attached a demonstation of the kind of sketches I made which consisted of  half a triangle with half a parabola fitted to it which was revolved to create the full 3d model of a blunt cone.

Any help would be greatly appreciated, Karen
