hi all
I got a question in the exam that required a surface gap to be filled and a fillet put in its place but as I don't use surfacing that much I didn;t have a glue what the best method to do it was so I left it. please could someone throw some light on this so I know for future. thanks

I have attached the model file and its the large are to be repaired and they state a fillet of 9.525mm

Sounds like too much work to me?
Blanket statement, merely a direction
..as Dave Dinius suggest... you'd need to take steps to remove (repeal) and replace... what I saw was the outside/offset shell is ~4.8mm from the inside.. so, I copied the surfaces I would need later, removed the outside, offset the inside 4.8mm and extended/untrimmed and filleted back the outside.
My attempt.
Edit: Oops, I missed this part of the problem description.
"...and they state a fillet of 9.525mm"
We was thinking along the same line. I made mine before I looked at yours J. Mather Not quite the same but close.....
now, I'm confused.. the inside surface fillet is at 9.525.. so,. the outside fillet is also 9.525?... . normally or wall thickness (~4.8) would make the outside ~14.33?
..btw,.. you made me think again about making this simpler...and, this can be done using a face fillet!... I honestly was surprised but it works with either the 9.525 or the 14.33!
I'm not sure if I understood it correctly, but I used a fill surface and stitched the resulting surfaces to the imported surfaces using the create solid option. I then used delete face (with patch option) and then added fillets.
I tried to find values
They want you to be able to use several different surface functions to be able to put the fillet on the part. You need to use some combination of Untrim, Trim, Extend, Knit, etc, functions. They have basically removed the fillets, you have to put them back.
