Hi Friends
Sometimes it's also nice to play with Nodes ........
in any case , with this test of SudSurf (which I must say works fine)
there are still some limitations:
1- Offset works well with low values
otherwise it produces artifacts
2- Extrude on Surf does not work
3- Intersect between SubDSurf and lines do not work
4- It would also be interesting and useful make Active option
Thickness in the Node Offset

Have a nice week to all and good Work
best
al
Ps-I can not put all the files ..
how can do ?....
I'll try to make send separate ...
........some other solution?
