Need help with modelling a cylinder with a piece cut out? I need to model a cylinder with a piece cut out (a quarter of it), but I can seem to get it with nice edges: 

Test 1: Even with the a bevel added, the middle part is distorted.




Test 2 Added more mesh to the top to 'fix' it, but the mesh at the bottom is ruined.
I think this topology doesn't work too bad. You'll have to move a bit some edges to prevent a bit of pinching, I don't know if it can be perfect with an only 12 vertices cylinder though.
