Hi All,
I have a question regarding 3Ds Max poly extrude technique. While modeling I faced a problem lots of time and I try to find some solution but didn't get any thing. I know scriptspot is great community of max scriptors. So if any one can do something, will be great.
I have made a picture, which may describe the problem more elaborately.

Normal Cube with three subdivision.

Middle Polys are selected for extrusion.
