hi friends , meanwhile i began to model a pumpkin

i'm going to make is as a little project and render it too

....... i modeled up to below picture

i've got a little 2 questions about modeling ......
1) as u seen the blocks of the pumpkin.... i need to scale each pumpkin block itself horizontally ( to make it a bit smooth & round )....i went to the scale tool and i'm pretty sure that global mode doesen't do it ....and also the local mode only changes the orientation .....but as i said can we scale them horizontally each part itself ? ....i can do it manually but if we can do them at once it would be great


thanx

2) if i use "split edge" tool to split a one block (as seen in below picture ) ......how can i position the point at very sharp of the middle of that block ? .....i can guess and locate the point at the middle ... when i let the middle mouse button free, then it splits that block .....but can't be claimed that it splits the sharp middle of that block

plez give ur opinions .....thanx
