Can't do even fillets between extruded and lofted bodies

[snajper86]

Hallo

I've a pain in the eye with "Fillet" device. I have four bodies(two of them are extruded, the other two are lofted, I used "Loft" device) combined(joined) to one body. I do not know why the FILLET device is so fussy. I need fillets that are 8-9mm radius. On one pair of faces I can do those but on other similar pairs I can not. File is attached. Anyone can point me what am I doing wrong?

I did it with a mirror! 🙂

I can not use mirror because those lofted bodies are slightly different and placed in not even distances and there is more of them not two only.

Well that should be the principal problem fusion does not allow you to create the fillet, maybe you cannot create a fillet of that size in that geometry. 😕

The fillets interfere with each other.  You can do one or the other or redesign the part.

Your problem is in sketch 3, I went and added tangent constraints to the curves and both fillets will work at 8 or 9 mm. 

What I don't understand is how you can draw something and not use any dimensions. You sketches should be fully defined with dimensions and constraints, it will make your job easier and more reliable.

You were right. I have try to do that earlier(add tangent everywhere) but with no enough patient. In oryginal project I have them a lot. I deleta them and dimentions to simplyfy the sketch for forum purpose. Thank you! Adding tangent constraints  everywhere made it possible to do fillets.
