I can't be able to make a Projected Curve on my iron man helment.

I have a problem with my projected curve 11, I can't be able to make it out. It says it was an error. I would like to make a curve on these two line. I hope this would be an honor for your help.

Hi @kevin_lin238, looks like your off to a great start! When projecting two sketches, make sure the max and min geometry of the sketches line up properly. In this case, the lowest portion of your 2nd sketch was not horizontal with the lowest portion of your projecting sketch. Also, sometimes it is best to break it up into multiple projections. See the gif tutorial below:

I also notice that there are a bunch of lines in the side view which are drawn using splines, but they have no or almost no curvature. This will likely add unneeded complexity to the projected curves. I would recommend using straight lines for these instead, unless you think you will be adding some curvature to them later.
