Fillet

VM

Hello,

I am trying to fillet an edge more than what is currently being allowed. I am unsure what is restricting me from increasing the fillet. Any ideas or advice would be appreciate. Thank you.

In your initial revolve, you have a small radius of curvature 'S'-bend. I suspect the fillet tool doesn't like that. Perhaps making that a simple shoulder first, adding the fillet you want and then going back in and adding small radius fillets to recreate the 'S' would work.

Where all the fillets come together is a bit challenging. That may also be part of the problem.

You can diagnose what's causing the failure by splitting up your part into pieces and seeing if the fillet will work on one piece vs the others.
