Complicated shape adding a perfectly flat surface

PnG

Hi i am having a problem trying to add a perfectly flat surface to an object i am modeling. I am trying to go from a curved edge to flat along the sides then at the front it needs to curve down and be flat to the point where it looks like a boolean of a box into say a sphere would.. Adding geometry to the shape isn't doing me any good it just keeps adding lips.

Any help would be appreciated

It's hard to help out without any pictures! Could you upload some? It would make it easier for us to guide you!

I made the shape on the right from a box and then subtracted a rough shape with a boolean to get that shape. Now i am trying to model the same thing but keeping full controll so no booleans, however im stuck trying to create that perfect edge look (also the rest of the shape is off but thats how it needs to be)

The pink lines are the hold loops and the green the general topology. If this what you're looking for? You can also trying using (In Max) TurboSmooth with "by Smoothing Group" on if you assign different smoothing groups for each 'flow' of the mesh.
