Hi Pilou,

Thanks for the link to Glen Southern's tutorials.
I already knew them :)

Yes, with no dubt Silo is a mature software, but for me, comparison to NVIL it lacks in, at least, to main areas :

1) NVIL has the best tools for working with Edge creasing.

2) NVIL seems to be under very active development.

Anyway, thanks a lot, I appreciate your concern.

Ciao.
