groove creation on circular surface

[Strego]

Good evening to all,

Perhaps my doubt is a little trivial but unfortunately they are at first arms.
I would like to know how to make these three grooves on the circular surface. Thank you.

draw the profile of the groove and make a cut in revolution.

Maybe you should do the internal tutorials to the program

That was exactly what I thought. the problem is that I can't build the profile because I have a curve and not a drawing plan.
I made them tutorials but I didn't find traces of similar examples.

thanks for the answer,

next time you also express your solution ideas to allow a constructive comparison.

explain better

I made them tutorials but I didn't find traces of similar examples.

And I can't find them. tutorials give modeling bases, they are not a sample library. but if in your first post you ask how to do such a thing (which looks like a trivial circular cut), without wasting to provide you with information about the difficulties you encounter, it is to think that you are one of the many that opens the program and starts modeling on the head low

a very good thing

if the profile is curved at the limit you might think of using a sweep cut
