Well, in the *.dat file get the id of any 3d node. Then go to the *.sim file and make sure the id isn't already used as the Parent ID of a dial node. To make the object a proper dial, just look how the Dial nodes are structured. To make the object clickable there are 2 ways. You can either make the dial itself send a command, or, better, make a new object (there are tons of these dummies on the dials which are invisible but can be clicked) and apply to it a Focusable3Dobj node which can send a command. Again, it's not rocket science, just look how it's already made on the current nodes. The deck should work the same. Let me guess you want to click on the UZO and make it show?
When you want to work with a command like that, it's better to see how that command behaves in the commands.ini (or is it cfg?) file. You'll see that these commands that activate cameras also show the proper page of the 2D interface.
