What to do for the creation of the stop surface on the attached model?

Hi, I've been a solidwoks user for 3 years. I can't create the stopping surface on the attached model. How do I choose the right edges so as not to have redundant loops as solidworks tells me. I tried several selections but solidworks tells me that the loops are redundant.

What to do?

Hello, the version of the attached file is more recent, printouts screens or native file will be useful, 

Hello

The model's problem with the stopping surfaces is probably due to the complexity of the geometry of some shape details. In its search for contours to be filled, SolidWorks seems to lose the thread of its loops, and selects a number of edges that do not belong to holes to be closed.
The solution: turn off all the hole functions, reactivate them gradually, and at each step perform a manual selection of the contours. It's a bit long, but it allows us to identify the shapes that are problematic.
In the model I used, close to the original but with some modifications to lighten the build shaft, it is the small holes at the foot of the central rib that block the function, as well as the rectangular openings in the two end faces of the shell. Which in any case cannot come out of a mold in only two parts...
 
I didn't manage to get over this hurdle, but the other forms are well taken into account.
The model is attached, a certain number of surfaces still need to be stripped...

Kind regards.

Thank you Lynk for your reaction to my problem but I'm afraid that the images or the native file of this 3D model won't be able to fully show the difficulties I'm having. Here is an image attached

Thank you m.blt for your reaction. Your solution, of course, is tedious, but I'm going to adopt it since that's all I have on hand.
