Subassemblies falling apart in next assembly

For God's sake and my sanity, can anyone explain why, after jointing every component within my subassembly, it falls apart when added to its next assembly? I've use joints, as-built joints and rigid groups only to have it come in incorrectly or fall apart when I add motion in the next assembly, or even lock the top assembly from moving! I've wasted so much time having to re-joint the subassembly components within the next assembly.

Also is there a way to add multiple joints to a component?  For instance, having a tube t-fitting concentric to two separate tubes. Or having one component rotate relative to a 2nd component but always be parallel (perpendicular, at an angle) to a third component. Editing an assembly Is very difficult if jointed components won't move relative to each other and I'm constantly having to measure and move or "eyeball" and drag. I constantly get "the component already has a joint" and I'm like, "So, give another one". What am I missing?

 

Yes, I am used to being able to mate multiple parts together relative to other parts and those mates/parts being mirrored, moved, or otherwise relocated with a simple change, without my assembly puking all over itself, so please forgive my frustration.  Thanks in advance.

I started this project with invalid assumptions about F360. I appreciate all of the time you spent trying to educate (re-educate?) me. I'll probably get it given enough time.

 

Thank you.

I can join(t) the fitting to the first tube lengthwise but when I join(t) the fitting with the second tube, I get the message, hit yes and continue with the new joint. The second joint overrides the 1st and I end up dragging the fitting to make it look right.  I need the fitting to be concentric with both tubes without having to move them or editing the joint if I make a change. Again, what am I missing?

 

Also, how do you join(t) spherical components such that their surfaces remain in contact? I ended up join(t)ing the flat surfaces and eyeballing the contact. Of course it all failed when I had to make a small change.

 

Thank you again for your input and patience.

If you think a screencast will help I'd be happy to create a little tutorial.
