Hi Guys,

thank you so much for all your time and responses, I really appreciate all the advice you've given.

I tried your suggestions however I still have mixed results. I couldn't get the same results as you Phiro, how did you get all 3 edges filleted? My calculation always fails.

Thank you Michael for all the suggestions. I don’t really want to delve into adding more 3d/cad programs into my workflow just to do a single operation like filleting. For the sake of simplicity I’d like to stick with blender for poly modelling and MoI for nurbs.

I made the bottom part planar however I couldn’t fillet the bottom edge (calculation failed). Do you know if there are any definitive guides or golden rules for filleting to avoid the issues I’m getting? Perhaps it’s just sloppy modelling on my part :/

Thank you all again.

Cheers,
Jakub
