The second 2d sketch this time is on the front plane and not in the top plane. The reason for this is simply the direction of curvature of the model. If you look at this from the top it would be a straight line and you would not accurately mimic the curve. It will be up to you to decide which views to sketch in and it will take a bit of practice to pick up on this. Be prepared to do it wrong several times. Some compound curves may also require you to try a few different methods. There is nothing wrong with trial and error, so don’t get frustrated if you have to get it wrong a few times.
