The only problem I see using modo, is modeling this 2d shapes or complicated profiles that gets extruded to some thickness...is there something I am missing in modo or are these things just simpler using moi?

Hi Anna,

Also you have consider that Modo only handle polygon data as I know.

right, it is much easier to get precise shapes out of moi.
But it seems you want to have some 'soft' control as to how the shapes are bent, and here modo seems more appropriate.
I like using both apps, depending on the specific task.
in modo, you should create your 2d shape first, making sure you have a god edge flow (use only quads),
after you give your shape some thickness you can either use
edge weights , or use minimal edge loop bevels or extrudes to get a hard shape.
