I mean detailed pics like this: enter image description here

If it's impossible to get this information please try to describe an approximate structure. Also provide additional info if you can. Which metal are used? What extra features you know like something for safety? Which details were used as part of it? What is the detailed structure of Dragon?

    $\begingroup$ That may be difficult to come by. I've never seen a drawing that shows the internal structure of either. $\endgroup$ – Hobbes Jun 1 '16 at 11:19

The best that I can find available is the one that is released by SpaceX, as a somewhat interactive graphic on the Falcon 9 website. Here's a screen grab: enter image description hereClick on the blue plus signs when you're on the actual SpaceX page for additional details.

Why is there not a better diagram? Well, for a number of reasons.

First of all, SpaceX is known to change its configuration frequently for flight, meaning that the rocket breakdown might be flight specific to some extent. Granted, some things won't be changed on such a regular basis, but still, they are known for design iteration.

Secondly, there isn't a reason to release that specific of a diagram. The shuttle had its configuration released for a number of reasons, from attracting interest, to making sure all of the parts fit together as specified from a number of different contractors. Tax payers were paying for it, and wanted to know. SpaceX doesn't fit under those parameters, and as a commercial company, it is in their interest to not disclose the entire design to the public, as it could aid their competition. Also, such items must be released according to ITAR regulations, and there is cost associated with it.

That being said, we know of quite a few more things than are listed. There are thruster nozzles clearly seen. We know there are helium tanks inside. There are two tanks, one for LOX and one for RP1, the RP1 tank is the lower of the two. If you have specific questions, it's likely they can be answered as well.
