Smooth and mirror models

Maya
1

i created a object using the mirror tools but know i would like to smooth it.When i use the tools, Maya smooth every part of it not the complete object so, at the end, the object do not look like at what i want at all.
I would like to know how it's possible(if it's) to smooth the complete object.
Thank you for your answer(s)

P.S.:sorry for my preety bad english

Go into the options for the smooth and turn off the preserve smoothing groups and Uv's. I think there are a couple other options in there you want to turn off too. Just don't have maya in front of me right this sec to check.
