I was also looking a bit what Spaceclaim can do since lately i have seen few more people were mentioning it and using it.
Some really crazy ability which completely blurs the lines between cad and poly modeling since there is just so many
controls in Spaceclaim which alows you direct transformations of selections as poly modeling but with all the benefits of CAD modeling.

To go back to the topic (Fillet improvements) > you can just check this from Spaceclam and see how that fillet can not only go over the edge but over the
entire hole! > https://youtu.be/95vOhN2dTp0?t=1m9s

If you have time, please to check the entire video, so many things i guess Moi3D will never get or maybe somewhere in distant future.


Which kernel are they using to be able to do such things?
