How to fillet cylinder intersection?
Hi @ashes.man and thanks for uploading your model.
I guessed where your want to fillet, I hope I chose the right spot. I can make it work after some cleanup on your sketch geometry, Here's the process I followed:
First I noticed that there's a thin sliver face (highlighted in blue) where the cylinder joins its neighbours.
This is a warning sign that something hasn't matched up properly, difficult to manufacture and can cause trouble in features like fillet.
Before working to fix this problem, I confirmed that the fillet could work if I separated out the sliver region with a temporary cylinder I combined-in just for debugging.
Looking at the sketches, I found the defining curves for that silver face in Sketch1. Here's there is some unconstrained and not quite matched up geometry.
The sketch already has some constraints and constrained geometry (curves in black). The goal here is to properly constrain that blue arc and eliminate the mismatch with the nearby construction circle. Add some tangent constraints.
Revisit the solid model with this sketch fix and you see the sliver face has gone, the model looks cleaner and the fillet works.
My advice would be to try to make your sketches fully constrained where things nearly match up to avoid problems like this in the future.
Hope that helps!
