modify>convert>polygon edges to curves or simply run CreateCurveFromPoly in a mel console. after doing this you will also want to rebuild the curve, since it;s segments will be based on the amount of edges in the converted selection. edit curves>rebuild curve or RebuildCurveOptions in the mel console
