wierd prob
 

okay well sometimes when I extrude faces or edges then merge all the points to close the poly it works fine or it seems to.... but when i go to convert it into a subd mesh it gives me an error. So i open the script editor and it says to use the clean thing wich i do and it selects faces and when I move them there unattached so I merge the verts and try again and it continues to say that the faces aint attached. I have no idea whats cuasing this and I get around it by deleteing the face and rebuilding the parts that need to.. any one ever have this problem?
