I follow this simple tutorial on extruding multiple Curves but i don’t have the same result and i don’t understand why?
I made 2 curves circle and then i hit ctrl +j and then i extrude. I tried changing handle types without success.
Here the tutorial : https://www.youtube.com/watch?v=9fYCAqhJgss
Here my result :
Maybe you have to change the curve type to 2D?
Just tried it and it is the same, in the tutorial the guy is having the full blender logo as a curve and when he extrude he got capped surface for the whole logo.
OK got it, i had to first convert to mesh and then hit F to fill the surface and then extrude work.
I thought there was a way like in 3ds max to simply extrude multiple close curves into one single capped mesh.
Maybe an addon exist to do something similar anyone?
You can extrude curves, set them to 2 then extrude but ensure you set your fill. Here’s a small example.

@bloox64 is right.
The author of tutorial is importing an SVG. As a result, his curve object is a 2D Curve with fill mode set to Both.
You are the man! This make my day thank a lot!
Thank for the tip and file i now have a better understanding of how blender deal with bezier curve.
There is always a catch! When i hit the 2D button my custom curve collapse as a line, i tried to apply rotation and scale but still doing the same thing anyone have a clue?
There is a stack exchange here that mention applying rotation fix the issue but not with my custom curve since applying rotation just before hitting the 2D button yield the same result of a collapse line.

Can you show how it looks like? Maybe some parts aren’t closed, also depending of the complexity of the shiluette it might not be well draw, such as if there are curves overlaping or coming in an out of each other…
Yes i was doing a small gif to show and i have verify the curve if it was close and everything seem Ok.
This is starting to look similar to an issue in max where i was converting a mesh edge to spline and often i had to redraw the spline for some tools to work correctly so maybe it’s the same kind of problem here.
Ahh!! I think you have to rotate it so it sits on the XY plane, then aply the rotation and you’re done crossing fingers
Right on this one was a tough nut to crack but you finally did it! 
Thank again and is there a way to merge both of your post in one single solution?
I don’t think so, I’ll edit my first post tho, gload I could help you!
Thank for doing it since it was a very essential step to resolved the issue and it will help others i am sure!
Now i just need to finish this logo texture and playing a bit with the Eevee emission to get nice effect.
Nice to see your icon bigger, if you ask me, I would personally make make the nut a little bigger
