extract an edge curve that was made from a conic curve gives a spline rather than a conic curve
extract an edge curve that was made from a conic curve gives a spline rather than a conic curve
(OP)
In NX 7.5.5.4: When I extract an edge curve that was made from a conic curve or try to project it into a sketch it gives me a spline. I would like a conic curve. Any ideas or is it just the way it is. Can it be corrected in another version of NX.

Can you provide at least a picture, if not the actual part file, showing what it is that you're attempting to do?

It depends on if the feature can do analytical shapes and if the circumstance allows an analytical shape or not. - Rather than the NX version.
If you use the Extrude body with a conic , the edge will most probably be a conic. But if you sweep a conic using the Swept Feature, the result will most probably be a spline or a tolerant curve since the swept feature is designed to interpolate "any shape".
NX is, in my perception, good at producing the simplest / cleanest type geometry( i.e Arcs, conics) when possible instead of using splines / B-surfaces everywhere.
