Object to follow fillet

[joshuaYR7NA]

Struggling with something and been searching for a solution which I cannot find 😫

How do I get an object to extend with the fillet. Please see the picture for what I am trying to achieve and my drawing.

Would assume something to do with extending and following path?

I have attached the file.

Hi,

I had also found something in my stock and varied accordingly.

Maybe the 2. version (inside flat) is more what you want to achieve?

How would I go about curving the flat face inwards to match my image above?
