How can I draw this cylinder
I want to draw this picture, but I can't. My difficult is how can I make points on two circles of cylinder.

Hi,
can you post the code here, that you already have?
If it's just the points, we don't have to work on drawing a cylinder etc. if you might have that already, that's why I ask for the code.

Looks already good! Change this line
to that one, removing the unnecessary two last segments:
Stefan
\tkzDrawSegments[](A,D D,C E,G F,H)
