Fillet not working a 1 out of 4 corners

[iancLTBFX]

Hi All,

Attached is a relatively simple, symetric, low-pressure molded part which will happily let me put a 3mm fillet on 3 out of the 4 corners but the 4th corner simply will not play ball. No invalid edges. A 1mm fillet works fine on the corner in question but I cannot go larger. Can't see any feature that would prevent going to 3mm.

There's a 3 degree draft on external surfaces to help ejection.

Can anyone tell me how to get around this?

Many thanks.

• Create a mid plane.
• Split the model in half.
• Delete the problem side.
• Mirror the other side.
• Join the two bodies.

Thanks etfrench and guenther.andresen for the quick reponses. Both great ideas and worked perfectly.

Model now fixed. Many thanks.

Seems an issue with F360 that 3 out of 4 seemingly identical corners fillet perfectly and one chucks a wobbly.

I looked at your design and because you have no timeline there's no easy way to check on your work to see where the problem is coming from. Note none of your sketches are fully constrained, or even constrained at all!!

My suggestion would be in the future work with history enabled and fully constrain your sketches then if you run into a problem like this it will be easy to debug where the problem is. If it is actually a bug it can be fixed but as this design has no history no way to find where it's gone wrong.
