How do you convert polyline to contour?

Create a surface, open the definition tab, add the polylines (that have valid elevations) to the surface as Contour data. Note that contour data alone is not a preferred way to define a surface as breakline, point data and boundaries are absent and likely played a role in creating those polylines you call contours.
