thank you for the replies

It's like 'extrude faces' tool and 'scale' tool all in one. Exept when you do the exctrude face the edges come along. Otherwise can you tell me how to 'extrude face' inwards, with the edges?

Hi there, I'm a Belgian student and I'm translating from Lightwave to Maya. In Lightwave you got a tool called 'smooth shift', is there an equivalent to it in Maya?

thx
