Hello. First of all, thank you for the wonderful video and for the quick response. I am trying to make a small model of a boat (for further 3d printing), inspired by plans from a real boat (I am impressed of what I could do after 4 days of fusion). Anyway, I followed your tutorial regarding the boat and after I thickened the lofted surfaces, the boat looks wonderful except the parts where the faces connect. Could you please help me make the boat central axis (front and under) look smooth. If I had only one line, I could afterwards use maybe fillet to make it smooth... anyway, here is the file. Thanks a lot.
