Hello
Here is a tutorial that show how to model with circular fillet and trim ..

---https://www.animagraph.com.br/DeathBrain/Modeling/Fillet_Trim_Tutorial.htm---

I've followed all the step carefully

I can't get a good looking render..there is little ''crack'' between trim and fillet surfaces.. how i can get rid of this gap between surface ?

If someone can help on that ..it would be very nice..

Thank you in advance..
