T-fitting with one large dia

[hellomoto]

Help. I was able to model this Tee fitting easily. All ports are the same diameter. However, I need to make the upper port (labeled A) a larger dia (e.g. 2.5 inch). I am stuck now. Any suggestions on how to do this?

I tried creating sketches to do a loft, but I just can't get the intersecting joint right. If the upper port was perpendicular like typical Tee fittings, then this would be easy. so the question is, how to make this Tee fitting (shown in the second picture) but with an angled in-port instead of perpendicular, like the first picture?

Hellomoto,


I think it all comes down to how do you want that geometry to loft from 2.5" to 1"... In my case, I just created a similar intersection as shown in your second pic. Building it with surfaces, I used a "split line" to project my intersection curve with the existing 1" pipe... I built in a way that the angle was parametric, so this is the result:

Can you recreate this?
