Complex Surface

Hi everyone!
I’m struggling to create surface for this body.
I would highly appreciate any helpful advice or suggestion in solving this.
Please excuse my brevity, I’m not a native English speaker.


Here’s roughly what I did. I will admit, I couldn’t make the convex line sharp when I lofted. I think it’s possible using rails.

  1. Sketch
  2. rotate around axis (copy) the top line is the axis.
  3. constraint the lower line horizontal/vertical(the sketch you just rotated)
  4. Sketch a horizontal base line
  5. Extend rotated sketch to horizontal base line by dragging the end point (is why you constrained it)
  6. copy other original side
  7. use the translate tool to line up the sketch points.
  8. loft

Thank you very much!
