Thank you all guys for u comments. I'm gonna try what u told me about the proportion, but for now i got holydays to relax. But hey KBrown, i just have a question. You know when you use the Cut faces tool, you select the faces that u wanna cut and cut them. But after your selection still there. In my Maya the selection left and I need to select them again. It's really annoying and I tried to discover why and i didn't found anything. Thanks you again. cYa. i'll be back in 1 week.
