Subsurf Problem

Hello I have a question and hopefully someone can help me. I am modelling a space ship kinda thing and I need the cockpit area to be solid and not subsurfed. How can I just subsurf the rest of the model exept for the cockpit area. Here is the model http://img176.imageshack.us/img176/2919/testership1uf3.jpg

And here is the model when subsurfed:

select all the edges you don’t want subsurfed, then hit shift-e and make that crease value as high as you want.

Thanks Saxofoner that worked a treat. Cheers. :slight_smile:
