Hi. Im using autocad 2010 to draw 3d cylinders shaped like this
 
I ( I L I
 
i want to join I to ( so i can get something like J  but because im amateur i drew  those pipes in different dimension view and they're position all around the place and angles to the point that i cant find the correct angle to turn I so that it can fit into ( .
 
Is there an easier way to fit them without using rotation?
 

It would be much better if you posted a drawing file or, at the very least, an image.  A picture is worth a thousand mixed up words.
