How to tighten up mesh before subsurface mod added I'm modelling this detail and when I add the subsurface mod, it does odd things.  I cant make any loop cuts on it for some reason so have to use the knife tool.  Would I have to add alot of cuts to be able to get a clean looking mesh... any help on where to make cuts without creating ngons?
Select the edges you want to tighten and hit ctrl-b.
