Hi @all,
 
working since very recently with Inventor 2012. I've now designes a tube shape body, with a 30° angle. Easy until here
 
I want to join two of those tubes as assemble, but not as a straight tube (that's easy), I'd like to join them with the resulting 120° angle. I'm now trying since 3 days to find the proper constrains, but - for what ever reason - I'm not able to join them as I wish.
 
It should be easy - mate the two angle cuted surfaces, rotate 180° or.....?
 
Thanks for your help

I have uploaded (2) ipt's titled wye-01 & wye-02 in the Cad Blocks Section(under pipes) of this website that you may be able to used to get your assembly.
