Exercises to practice with complex curves?

[skanskan]

Hello

It's very easy to get exercises in pdf format with draftings of models made with simple geometries (extruded from sketches, revolved, straight lines, circles....).

But chould anybody give me some pdf with draftings useful to practice with more complex surfaces, please, please?
I guess they should have several sections of the model.
I mean, the drafting that you would give to a student with all information needed to create that model.

For example is typical to see a video where an instructor creates a spoon from it's silouette and several transversal sections.

I have only a suggestion.
Do an internet search and see what shows up on the college and university web sites. Many instructors post things on there.
