yeah, do what bullet suggested, get a screen shot (if you're on a mac then cmd+shift+4 then spacebar then click on the maya window to take a snapshot of it, the picture appears on your desktop. otherwise as bullet said PrtScn then ctrl+v in MSPaint or other picture editing program then crop it for windows)

but a crease? not sure what you mean. perhaps you merged the vertices and you've a funny combination of soft and hard edges?
