Hi JL, so the tricky part is the surface of a cello isn't just a flat plane and it isn't even curved in only one direction like extruding a 2D curve straight out will produce.

To make a curved surface like that you would need to position some cross section profile curves and then use a surface construction tool like Loft:

or Sweep:

to construct a curved surface.

The other thing is that you generally will want to make the loft to be a larger sheet which then will get trimmed to your top 2D outlines, rather than trying to construct a surface directly to those outlines. See here for an example:

Hello Michael,
thank you so much for your quick reply.
Yes, I know it is a difficult think and more difficult for a newbie.
Will take a look at the examples, let`s see whether i can work it out.

Best wishes
