I started playing with it and I have the crevisis you are asking about. you should start a project here and upload your file. I saved my version but I am using a SW 2012 so I don't think you will be able to open it so here is how I did it.

1. Step 1:

   I opened a sketch on the plane you created. (the top of the ribs)
   

   

2. Step 2:

   created a rectangle the size I wanted and made sure it was large enough to touch both the rim and the inner high part.
   

   

3. Step 3:

   extruded to the bottom surface with 5 degrees of draft
   

   

4. Step 4:

   created an axis using the front and right plane
   

   

5. Step 5:

   did a circular pattern (under the linear pattern button)
   

   

6. Step 6:

   did a second circular pattern the other direction (click on the arrows to the left of the axis to change the direction)
   

   

7. Step 7:

   added some fillets
   

   

8. Step 8:

   and a few more fillets
   

   

9. Step 9:

   and this is what we have.
