Create a pipe connection with From 3 circles

I’m trying to find the easiest way or the most efficient way to make this pipe connection.
Any ideas ?

Thanks in advance :slight_smile:


Hi Jeff -

The easiest way would probably be to use a SubD object, but that won’t give you perfectly circular profiles at the outlets. Apart from that, a T-joint is a special case of a Y-branch, which is something that has been frequently discussed here - Search results for 'y-branch order:latest' - McNeel Forum

Something like this?



Yes !!! Have you done this with NURBS ?

Thanks Wim for your reply,
I’ve followed a tutorial with Sub-D to make this but I’m not a big fan to be honest and through this discussion, I wanted to make this with NURBS.

I’ve found a way by cut circle in quarter.
and split curves with same numbers of point and join them by another curve and after create a surface which worked but way too long.

The way of ROLF is way more efficient than mine :slight_smile: thanks for that !

did you post / send a file somewhere ?

is this topic solved ?

as the question was for a easy solution:

Yes. @Tom_P shows in more detail how to do it.
