Wire with SubSurf doesn't follow surface in Edit mode How do I smooth the grid along the mesh? I've been looking for the answer all day and I couldn't find anything.
Click on the triangle with vertices icon - last one on top row of SubSurf modifier panel. 




Not always you want to have it enable in Edit mode since it can be sometimes quite confusing moving vertices affected by modifier. SO if you will have difficulties disable it to check situation.
