Not sure if you just want to know how to turn this on or a tutorial in how to use it ? (can't give you the tutorial but you turn it on in the properties box - right click the object/choose properties and the real time smooth/mirror features are in there (took me a while to find - but I never read instructions if I can help it ))
Thanks Alan, thats all the info I needed. I played with the settings in here before but was pressing commit all the time, which I think now is the same as the smooth operation. Just don't commit ;D Well I think I'll go and play with this for awhile thanks again
