Another problem I have with these extrude faces is the vertices don't seem to be connected. If you grab an edge and lift it just peels off and doesn't raise the whole object. If you merge vertices then it seems to work normal. What the heck am I doing wrong??!! This is the first time I am using extrude face, normally I just split poly and go from there. For what I am doing now that would be more time consuming. Is there some setting with extrude face I am missing?
