problem in making 3d model from a sketch

[Anonymous]

hi guys, i practically finished making the outline of my sketch, so i went to model, i selected the revolve button i gave it the commands and i got the model i wanted but then going to look better i saw that some lines remain visible of the sketch, what is it due to? I did something wrong in the sketch? how can I fix it?
thank you

Not sketch.

Face boundary = ignore.

The lines are the edges of faces and are normal, you did not do anything wrong. You can change the visibility from shaded with visible edges to shaded to see the model without edges.
