okay got it thanks Mat

i seen the vertics and finally just blew out all them in that one spot and then look at vertices face and everything was seperated again.

one huge question i cant get answered. If i have a polygon and i move one vertice there is another one that is left ..is that normal ? here is a pic

i just moved two vertices and do you see the other lines still left behind ? is that normal . i didnt do the square and pick it . i just click the mouse on the vertix . am I doing it wrong ?
