How do I design this oil container

[Mans]

Excuse me that I encounter this issue emotionally.

I am uneasy and even angry at myself because of some of my failures in designing. I tried to recreate this 4 Litter oil container but I couldn't find a way to create its complex curvature edges with different angles.

Is there anyone to take me out from this problem and confusion, please?

I'm very willful person to find a way in the technical problems, unlike physical activities that I'm among the lazy ones LOL

After a nonstop effort during two days and night, I eventually could to design the container. The method I found is not particular to this object, but it is a method that will help me to design other complex things in Generative Shape Design! I actually am happy for this success. This caused I think, I'm a talented technician and designer!

Although nobody helped me in this case, but I give thanks to you, my colleagues
