Hello, I am very new to modeling and need to pointers and suggestions for this particular shape I want to model. Here is an image of what I am trying to make (http://imgur.com/rt19Y).

I have a tube/cylinder that will split and turn into a plane. The grey area is the bottom, underneath the plane.

Any advise on how to do this? Thanks in advance!

1 try with a cylinder and proportional edit

2 - could be done with boolean if you have 2 appropriate shapes
like one cylinder plus another shape to cut the cylinder!

Ah, I see. I like proportional editing so far. I did this and made the modeling a lot easier.

Thanks
