Extend Fillet

[MichaelBurnsBITLLC]

Is there a way to extend the fillet beyond the plane perpendicular to the fillet line?

I know that I can sketch and extrude the same feature, but I would first like to confirm I am not missing an easier method, since this issue pops up a lot for me. Thank you.

Normal circumstances, Fusion should have done what you want.

Attach your data for testing.

Might help….

I posted the file. Copy/pasted the component into a new design because I do not want to share the full design publically. This created two sketch warnings but the sketch plane and projections are complete/defined in the original design, without warnings.

I also just did a check and it seems to me this is normal behavior. Here's another example.

should work the way you want.  some times fusion chokes on this one the geometry is to complicated.  in this case b/c a spline was used. if you simplify the curvy profile and use arc in the region when you want the fillet to extend out this does work.  see attached where I added an arc to one side of your eample.

  I don't know if this is in the realm of bug or limitation. @Phil.E ?

Unconstrained sketches.

Unnecessarily duplicated dimensions...

My testing has the same results, and I would expect the result you are looking for.

There are workarounds, that should not be necessary.

Can you fix the fillet result?

[TheCADWhisperer]

I would have to start over from scratch as I don't trust unconstrained geometry and highlighted issues.

Given that this dummy file is an extraction,

Ok, found the test file.

Thank you I will consider that arc solution in the future. I was also able to achieve the desired geometry by deleting the face comprising the end of the fillet. But that is a non-preffered workaround.

[MichaelBurnsBITLLC]

Thanks for looking at this. Yes, deleting the face comprising the end of the fillet results in the desired geometry. 

[MichaelBurnsBITLLC]

Fair points but I don't belive they are causing the issue.

[MichaelBurnsBITLLC]

Thanks for looking at this. Yes, the easiest workaround seems to be to delete the face comprising the end of the fillet. But if this issue is consistent for splines extruded perpenducular to and joined with a base feature it may be useful to log it as an improvement oportunity.
