I really hope somebody can help, I'm in a bit of a difficult situation. I'm trying to model a concave organic shape. I'm at the step now where I need to cut away the corners in order to have a overall smooth side, but i need the top part to be straight, because it's going to function as a table. I will try to add a sketch so it hopefully make more sense. I also add the SW file, where you can see i alverdy have begun to cut away the top, but i believe there should be an easier method.
