Hi, I'm looking for a bit of help with a fillet feature.

Fillet 11 is used to fillet the edge in the middle of the pic, but it won't continue the fillet leaving a sharp point.

This model is created as a quarter and then mirrored twice. I can correctly fillet one of the mirrored edges, but not all of them!

This may be easier to fillet while still a surface, but I'm not fully up to speed with surfacing, apologies if it looks a little messy!

Thanks

Michael
