How can I achieve a smooth fillet between both surfaces here, in a way that guarantees G2 continuity? I tried with the blend, nsided and network tools but they didn't work as expected.

It should be possible because the curves to blend were made by splitting both intersecting surfaces with a spindle-like symmetric object (made by revolving a profile along an axis) flowed along the intersection curve.

Hi geekmidget, select the inner cone piece and then run the merge command on it (press tab key to put focus in XYZ bottom input that works like a mini command line, then type merge and then <enter>).

Then there will be just one edge on each object, select those and then you can do Blend.

When there are more than 2 edges and they are all touching each other end to end Blend will have some difficulty in automatically sorting them.

You have 2 edges against only one on the surface so.. :) and Micheal is always more speedy than me! :)

And because i don't remember the Merge method :)
so my long method :)

Move Extract the 2 edges + the close circle Edge
Join the 2 edges it's now 2 curves !
Straight Loft the 2 Curves
Replace this repair against the false original



Here with Blend no problem after repair!

Awesome, thank you both!
