I’m trying to subtract a circle from this body, but I can only select it if I hide the body is there another way?

If I understand that you do not want to affect the inner cylinder…then do this.  
Do a split-body at the inner bottom surface and temporarily hide the inner cylinder. Do the subtract as you like. Then unhide and union.

No that is fine, I want to select the whole circle but the image you can see that I can only select the half that is not inside the body, for selecting it all I need to hide the whole body.

I usually just hide the body, select the profile, show the body, and only then invoke the operation I want to do with the profile. Another option is to use the profile as a cross-section plane. Even though you’ll only see half the body, any operations will be done on the whole body.

May be there is a crossed line what split your circle?

I generally do it as TheBum suggested. hide the body then you can select the whole sketch inner circle. Then unhide the body.

Yes I do have a construction line that splits the circle. so for this case I need to hide the body to select it, correct?

I wish shapr3d had the hold to select the element like in fusion360

The construction line shouldn’t cause this, because it’s not “really there”.  
Strange…

How did you made the rings, extrude from offset circles or revolve cross-sections?

You are right it works with the construction line no problem, I’m not sure what I did wrong but I can’t reproduce it anymore
