Patch surface issues

[vyrtech3]

Hi everybody

Could you be so kind and help me to connect surfaces? I was using Creo Parametric and here in Autodesk® Inventor® 2023 it is little bit different :). Please see a ipt as attachments

I wouldl like to connect two circles (dia140mm) on the to with the one on the bottom (dia240mm). 

Have a nice day

Here's my attempt, saved in 2026 version of Inventor.

Edit, I also attached the file in stp format

here's another attempt. Smoother transition from the two forks to the main cylinder.

Hi! There are multiple ways to create the geometry. Here is one solution without using Loft, Boundary Patch, or Freeform. I tried honoring the design intent as much as possible. The geometry at the junction is undefined. As long as the transition is smooth, it should be fine. However, you may need to run CFD Analysis to ensure the fluid handling performance is acceptable.

Many thanks!

Hello

Thank you very much. It looks very good. The thing is i would like to learn it how you make it. Is it possible to make process video maybe?

Would you be so kind?
